Help me Compiling CyanogenMod 13 on Ubuntu 16.04 - Android Q&A, Help & Troubleshooting

Hi developers. I am very much newbie to whole android development and trying to learn how android works and compiling a rom for myself. Can somebody make a tutorial about compiling CyanogenMod 13 in Ubuntu 16.04 with open jdk 8 ? There are many written tutorials in internet and different guides have me different command instructions. And the android official porting guide is confusing to me. I have no prior knowledge in Java and not much in Linux commands. I am stucked at Initializing my build environment. I have downloaded the compressed source code of CM 13 from this http://forum.xda-developers.com/android/software/sources-android-sources-highly-t3231109 and extracted to a working directory naming "android"
Now after extraction, this folder contains a .repo folder containing 12GB of source code.
(whats the actual size ?)
Then followed this tutorial https://nathanpfry.com/how-to-setup-ubuntu-16-04-lts-xenial-xerus-to-compile-android-roms/
then at android dir, which is my working directory, typing these commands gave me errors attached below.
proceeded to bashrc steps without any problem, then when I typed repo init -u https://github.com/CyanogenMod/android.git -b cm-13.0 to initialize the repo, got an error message attached below. (5th attachment)
Well. As I already have those source codes in .repo, and extracted inside my working directory 'android' so I run repo sync commands which gives me an output attached below. (2nd attachment)
Then after typed these commands
cd .repo/manifests
git fetch origin
git reset --hard origin/cm-13.0
repo sync
And it started to download few things again and
gives me another result with an error (Attached below 3rd attachment).
Then typed cd vendor/cm/
it gives me a shock by no such file or directory exists. See vendor error.png attachment and I am stucked. (4th attachment)
no commands taking properly after that.. prebuilts commands stated as invalid, no device specific code downloaded (I am using a Micromax Bolt Q370 device), no breakfast command taking.. nothing. I am stucked. Whats wrong I am doing ?
I have downloaded 12 GB of data.
(Mobile Data is so expensive)
P.S. I am also uploading some snapshots of my Ubuntu home and working directory so that you can understand what's wrong with no such file or directory error. I dont want to download the whole source code again, and point me out if I am acting like a noob. Your guides will be appreciated and grateful. Have a good day.

I haven't compiled a Rom before? But none of the guides you linked are from source.android.com. Best to do a "make clean" and follow the offical guide provded by Google and adapt as needed. Also for a functioning Rom you'll probably need the proprietary binary blobs for your phone.
Best thing about the android/Google guide is that they are using ubuntu, and assume that you are to, so the guide is specifically aimed for ubuntu, making your life easier.
https://source.android.com/source/index.html

The android source guide is bit complicated for me as I am new to both git and repository things.
A video for CM 13 with a step to step guide will be appreciated at current time. I think it won't be a problem who already has repository installed and built CM 13 before.

Dont use openjdk 8, use 7 as of now 8 is still experimental.
You can try build without sync it first. Just use whatever comes from extracted tar.xz. add your device, kernel, vendor tree. Do source build/envsetup.sh , add_lunch_combo , lunch and then make otapackage.
Please check CyanogenMod build wiki.

Terminal is not taking build/env command. Well buddy, do you have cm 13 repo ?
Check out my attachments. The directories. Are they missing anything ?
The Wiki and Android Source page guides are confusing to me. Sorry I am a beginner but determined to learn

Sorry, I based my previous comment for non-repo archive. For .repo folder you should try to extract the source first and then proceed with build/envsetup.sh, etc, etc

.repo is aleady extracted to my working directory 'android', contains 13GB of source code.
Now if i give envsetup command, my linux terminal doesn't understand it and responses an invalid command error.

Somebody said me that openjdk 7 is incompatible for CM 13

I am done with repo sync but there are many questions in my mind and things to learn. I made a separate post of these question here http://forum.xda-developers.com/android/help/questions-compiling-cyanogenmod-13-t3496186/page1

Guide on how I build my own CM9 test builts

A follow up on this - http://forum.xda-developers.com/showpost.php?p=28177937&postcount=1768 - in the CM9 FXP thread, have I promised to make a little guide.
Guide how I build CM9 for my Mango.
For the first time you try to build CM9.
Create ~/bin and download repo to that directory. Afterwards set executable bit to make it possible to ”execute”.
Code:
mkdir -p ~/bin
curl https://dl-ssl.google.com/dl/googlesource/git-repo/repo > ~/bin/repo
chmod a+x ~/bin/repo
Now reboot the computer.
Create ~/android/system amd initialize the repository.
Code:
mkdir -p ~/android/system
cd ~/android/system/
repo init -u git://github.com/CyanogenMod/android.git -b ics
repo sync
Setup the environmental settings and initialize the Mango build.
Code:
. build/envsetup.sh
brunch mango
Setup the environmental settings and initialize the Mango build.
Code:
git clone git://github.com/TheMuppets/proprietary_vendor_semc.git -b ics ~/android/system/vendor/semc
cd ~/android/system/device/semc/mango/
./setup-makefiles.sh
Download the prebuilts
Code:
~/android/system/vendor/cm/get-prebuilts
Check for new changes
Code:
cd ~/android/system/
repo sync
Setup the environment again and build the ROM (takes long time)
Code:
. build/envsetup.sh
brunch mango
You will now find the build here (change DATE into the date).
~/android/system/out/target/product/mango/cm-9-DATE-UNOFFICIAL-mango.zip
The next times you try to build it, you only need to do the following.
Delete build.prop, if not will build.prop not get generated.
Code:
rm -f ~/android/system/out/target/product/mango/system/build.prop
Syncronise the git repositories.
Code:
cd ~/android/system/
repo sync
Setup the environmental settings.
Code:
. build/envsetup.sh
Configure/build.
Code:
brunch mango
You will now find the build here (change DATE into the date).
~/android/system/out/target/product/mango/cm-9-DATE-UNOFFICIAL-mango.zip
If you are trying to build it on a 32bit system, you should change line 374 in ~/android/system/device/semc/msm7x30-common/releasetools/common.py
from:
Code:
cmd = ["java", "-Xmx2048m", "-jar",
to:
Code:
cmd = ["java", "-Xmx1024m", "-jar",
If you get into any trouble, please let me know, I may have missed something.
EDIT (July 2. 2012): I have made a patch to msm7x30-common, so you do not need to edit the file (with this patch does it automatically check if you run on a 64bit or a 32bit system):
http://code.google.com/p/freexperia/issues/detail?id=527
EDIT (July 6. 2012): If there has been an update on git://github.com/koush/proprietary_vendor_semc.git (like there has been today), shall you do the following (pull the updates):
Code:
cd ~/android/system/vendor/semc
git pull
EDIT (July 8. 2012): Adding the following, just before "</manifest>" in ".repo/local_manifest.xml" and the proprietary files will also get updated, when you make a normal "repo sync". Got this idea after talking to Andreas (so thank you Andreas).
Code:
<project name="TheMuppets/proprietary_vendor_semc" path="vendor/semc" remote="github" revision="ics" />
EDIT (July 11. 2012): Changed the proprietary repository from git://github.com/koush/proprietary_vendor_semc.git to git://github.com/TheMuppets/proprietary_vendor_semc.git
allright, i have already synched the cm9 repo. about 5.8 gbs
can you tell me what folders does it include?
edit:took me a few days to download, just don't want to download again

Are you thinking of the "clean" repo?
My ~/android/system/ consists of the following (remember the hidden directories):
abi
android
bionic
bootable
build
dalvik
development
device
external
frameworks
hardware
kernel
libcore
ndk
out
packages
prebuilt
sdk
system
vendor
.repo
.repoconfig
Makefile
You should be able to move your current directory and "just" sync it, to get it up to date.

They are possibly first created when running brunch the first time. So it should be fine.
successfully building, but getting loads of warnings..
is that normal for the first build?
will report if it boots after compile is over.

There are lots of warnings.
Personally I usually remove all that warnings (using the -Werror option, so warnings get treated as errors) in the projects I am working on. But I understand why it can be a big problem with CM9, that is based on many different projects.
Looking forward to hear if you get a successful built.

building will take some time...
well, most warnings are 'some variable has been set but not used', is that much significant?

Yes, first build takes a lot of time... the next times it will be a lot faster.
No that is not very significant, but things like that should still get fixed, to to make it easier to find the significant things.
The less warnings the more easy it is to spot what is important. This also goes for things that should get changed when upgrading to a new major version of the toolchain.
succesfull build!

running fine.
but i see some dependencies missing from the libs needed from
http://wiki.cyanogenmod.com/wiki/Template:Build_from_source_(CM9)
downloading them, will build again later..
is that the reason for the warnings?

looks like a nice guide that is working with most devices, will save that link
No, the warnings are simply that you rarely find "clean" code, where most warnings have been fixed.
You also need to think of all the code from external projects.
You also only get many of the warnings, if you do not compile the code for some specific platforms.

saw that guide after i started checking for dependencies.
1.hey i see two zips in the output,
one cm-9-20120702-UNOFFICIAL-coconut and other cm_coconut-ota-eng.gandhar
the second is bigger.
i used the first one. why is the second one built i wonder?
2.i think of compiling aosp from source too, but the out folder is 11.3 gbs, what about that?
i do not want to end up falling short on space.
3.this is a system related question, how much will it hinder performance if i move the source to a different internal hd from the main one and build from there?

You could do a "make clear", but if you have enough space, would I keep it, so you do not need to wait for the already up to date files.

There will be no problem with performance, as long as you move it to a HDD that is not too slow.

Have not tried that.
You can try to do a "repo forall -c git reset --hard" this "resets" all the repositories (removes all changes, also if something has been corrupted).

Local Manifest Help

Hey, i am from India. I am trying to compile a CM13 ROM for my device Micromax Q370 following XDA University guide. Well. There is no such fork available for my device in git. Well. I am done up to repo sync state successfully. But stucked after that. No idea about making device specific tree or adding a local manifest xml file. Whenever I give the command " $source build/envsetup.sh ", after repo sync process completes, I get an error with bash build/envsetup.sh : no such file or directory. same with Vendor/cm command also.
Whats the fix ?

How-to Build LineageOS​
Introduction​
These instructions will hopefully assist you to start with a stock device, unlock the bootloader (if necessary), and then download the required tools as well as the very latest source code for LineageOS (based on Google’s Android operating system) for your device. Using these, you can build both LineageOS and LineageOS Recovery image from source code, and then install them both to your device.
It is difficult to say how much experience is necessary to follow these instructions. While this guide is certainly not for the very very very uninitiated, these steps shouldn’t require a PhD in software development either. Some readers will have no difficulty and breeze through the steps easily. Others may struggle over the most basic operation. Because people’s experiences, backgrounds, and intuitions differ, it may be a good idea to read through just to ascertain whether you feel comfortable or are getting over your head.
Remember, you assume all risk of trying this, but you will reap the rewards! It’s pretty satisfying to boot into a fresh operating system you baked at home . And once you’re an Android-building ninja, there will be no more need to wait for “nightly” builds from anyone. You will have at your fingertips the skills to build a full operating system from code to a running device, whenever you want. Where you go from there– maybe you’ll add a feature, fix a bug, add a translation, or use what you’ve learned to build a new app or port to a new device– or maybe you’ll never build again– it’s all really up to you.
What you’ll need
* A device (supported by LineageOS)
* A relatively recent 64-bit computer (Linux, OS X, or Windows) with a reasonable amount of RAM and about 100 GB of free storage (more if you enable ccache or build for multiple devices). The less RAM you have, the longer the build will take (aim for 8 GB or more). Using SSDs results in considerably faster build times than traditional hard drives.
* A USB cable compatible with the OnePlus One (typically micro USB)
* A decent internet connection & reliable electricity
* Some familiarity with basic Android operation and terminology. It would help if you’ve installed custom roms on other devices and are familiar with recovery. It may also be useful to know some basic command line concepts such as cd for “change directory”, the concept of directory hierarchies, that in Linux they are separated by /. etc.​​
Summary
1. Install SDK
2. Install build packages
3. Java
4. Create the directories
5. Install the repo command
6. Initialize the LineageOS source repository
7. Download the source code
8.Prepare the device-specific code
9. Extract proprietary blobs
10. Turn on caching to speed up build
11. Configure jack
12. Start the build
13. Install the build
Build LineageOS and LineageOS Recovery​
1. Install SDK
If you haven’t previously installed adb and fastboot, you can download them from Google. Extract it using:
Code:
unzip platform-tools-latest-linux.zip -d ~
Now we have to add adb and fastboot to our path. Open ~/.profile and add the following:
Code:
# add Android SDK platform tools to path
if [ -d "$HOME/platform-tools" ] ; then
PATH="$HOME/platform-tools:$PATH"
fi
Then, run this to update your environment.
Code:
source ~/.profile
2. Install build packages
Several packages are needed to build LineageOS. You can install these using your distribution’s package manager.
You’ll need:
Code:
bc bison build-essential ccache curl flex g++-multilib gcc-multilib git gnupg gperf imagemagick lib32ncurses5-dev lib32readline-dev lib32z1-dev liblz4-tool libncurses5-dev libsdl1.2-dev libssl-dev libwxgtk3.0-dev libxml2 libxml2-utils lzop pngcrush rsync schedtool squashfs-tools xsltproc zip zlib1g-dev
For Ubuntu versions older than 16.04 (xenial), substitute:
libwxgtk3.0-dev → libwxgtk2.8-dev
3. Java
Different versions of LineageOS require different JDK (Java Development Kit) versions.
LineageOS 11.0-13.0: OpenJDK 1.7 (install openjdk-7-jdk)*
LineageOS 14.1: OpenJDK 1.8 (install openjdk-8-jdk)
* Ubuntu 16.04 and newer do not have OpenJDK 1.7 in the standard package repositories. See Ask Ubuntu question How do I install openjdk 7 on Ubuntu 16.04 or higher Note that the suggestion to use PPA openjdk-r is outdated (the PPA has never updated their offering of openjdk-7-jdk, so it lacks security fixes); skip that answer even if it is the most upvoted.
4. Create the directories
You’ll need to set up some directories in your build environment.
To create them:
Code:
$ mkdir -p ~/bin
$ mkdir -p ~/android/system
5. Install the repo command
Enter the following to download the repo binary and make it executable (runnable):
Code:
$ curl https://storage.googleapis.com/git-repo-downloads/repo > ~/bin/repo
$ chmod a+x ~/bin/repo
Put the ~/bin directory in your path of execution
In recent versions of Ubuntu, ~/bin should already be in your PATH. You can check this by opening ~/.profile with a text editor and verifying the following code exists (add it if it is missing):
Code:
# set PATH so it includes user's private bin if it exists
if [ -d "$HOME/bin" ] ; then
PATH="$HOME/bin:$PATH"
fi
Then, use this to update your environment.
Code:
source ~/.profile
6. Initialise the LineageOS source repository
Enter the following to initialize the repository:
Code:
$ cd ~/android/system
$ repo init -u https://github.com/LineageOS/android.git -b lineage-16.0
7. Download the source code
To start the download of the source code to your computer:
Code:
$ repo sync
The Lineage manifests include a sensible default configuration for repo, which we strongly suggest you use (i.e. don’t add any options to sync). For reference, our default values are -j 4 and -c. The -j 4 part means that there will be four simultaneous threads/connections. If you experience problems syncing, you can lower this to -j 3 or -j 2. -c will ask repo to pull in only the current branch, instead of the entire LineageOS history.
8. Prepare the device-specific code
After the source downloads, ensure you’re in the root of the source code (cd ~/android/system), then type:
You have to change DEVICE with the codename of your device (for example: Oneplus ONE codename is bacon)
Code:
$ source build/envsetup.sh
$ breakfast "DEVICE"
This will download your device’s device specific configuration and kernel.
Important: Some maintainers require a vendor directory to be populated before breakfast will succeed. If you receive an error here about vendor makefiles, jump down to Extract proprietary blobs. The first portion of breakfast should have succeded, and after completing you can rerun breakfast​
9. Extract proprietary blobs
Method 1
Now ensure your device is connected to your computer via the USB cable, with ADB and root enabled, and that you are in the ~/android/system/device/your_device/codename folder. Then run the extract-files.sh script:
Code:
$ ./extract-files.sh
The blobs should be pulled into the ~/android/system/vendor/your_device folder. If you see “command not found” errors, adb may need to be placed in ~/bin.
Method 2 (Recomended)
Search for your device blobs on TheMuppets or Donkeycoiote and add them to local manifest
10. Turn on caching to speed up build
You can speed up subsequent builds by running:
Code:
$ export USE_CCACHE=1
And adding that line to your ~/.bashrc file. Then, specify the maximum amount of disk space you want cache to use by typing this from the top of your Android tree:
Code:
$ prebuilts/misc/linux-x86/ccache/ccache -M 50.0G
Where 50G corresponds to 50GB of cache. This needs to be run once. Anywhere from 25GB-100GB will result in very noticeably increased build speeds (for instance, a typical 1hr build time can be reduced to 20min). If you’re only building for one device, 25GB-50GB is fine. If you plan to build for several devices that do not share the same kernel source, aim for 75GB-100GB. This space will be permanently occupied on your drive, so take this into consideration. See more information about ccache on Google’s Android build environment initialization page.
11. Configure jack
Jack is the new Java compiler used from Lineage 14. It is known to run out of memory
Simple fix is to run this command:
Code:
$ export JACK_SERVER_VM_ARGUMENTS="-Dfile.encoding=UTF-8 -XX:+TieredCompilation -Xmx4096m"
Adding that command to your ~/.bashrc file will automatically configure Jack to allocate a sufficient amount of memory.
If this doesn't help, you can reduce the number of Jacks to 1 in config.properties

12. Start the build
Time to start building! Now, type:
Code:
$ croot
$ brunch [COLOR="red"]device[/COLOR]
Remember, device is the codename for your device
The build should begin.
13. Install the build
Assuming the build completed without errors (it will be obvious when it finishes), type the following in the terminal window the build ran in:
Code:
$ cd $OUT
There you’ll find all the files that were created. The two files we’re interested in are:
recovery.img, which is the LineageOS recovery image.
lineage-14.1-build_date-UNOFFICIAL-device.zip, which is the LineageOS installer package.
Success! So… what’s next?​
You’ve done it! Welcome to the elite club of self-builders. You’ve built your operating system from scratch, from the ground up. You are the master/mistress of your domain… and hopefully you’ve learned a bit on the way and had some fun too.
Now, what to do next? You can jump to next section of this guide to understand how Github works and how to pick some commits from other developers/teams to improve your custom ROM​
This guide was taken from Official LineageOS wiki and all credits goes to LineageOS Maintainers ​
What is Github and how to use it
GitHub is a code hosting platform for version control and collaboration. It lets you and others work together on projects from anywhere. It is a powerful tool with many features available and here i´m going to talk about how you can use it to help you build and customize your "Custom ROM"​
Summary
1. Repositories
2. How to add/remove repositories
3. How to add/remove remotes
4. Repository Fork
1. Repositories
Now that you have built custom lineage from source to your device, you can explore deeper and see how things work and change them according to your needs.
First we are going to se what is inside .repo folder
Code:
cd ~/working_dir/.repo
ls
It will show you something similar to this:
Inside the .repo folder are the necessary "manifest files" that tell the repo sync command what to include or remove from our project when synchronizing with the source
Open manifest.xml
Code:
gedit ~/working_dir/.repo/manifest.xml
Inside that file you have all information about which repositories belongs to source. These are the base repositories to build LineageOS.
Inside ~/working_dir/.repo/local_manifests/roomservice.xml you can see the repositories needed to build for your specific device. This file is created after breakfast device step and includes, besides others, device tree and kernel.
2. How to add/remove repositories
Lets take a look at how we use roomservice.xml to add/remove repo's from our project, i will use Oneplus ONE device tree for example
Code:
<project name="LineageOS/android_device_oneplus_bacon" path="device/oneplus/bacon" remote="github" revision="cm-14.1" />
* project name="LineageOS/android_device_oneplus_bacon Name of repository (without https://github.com)
* path="device/oneplus/bacon" Here is where the files will reside in our working directory
* remote="github" Is the for remote we are using, in this case is github (see below how to add/remove remotes to your project)
* revision="cm-14.1" Revision is the branch we want to sync
Image:
3. How to add/remove remotes
Code:
<remote fetch="https://github.com" name="github" />
* remote fetch="https://github.com Url for remote you want to add to your project (in this case, we are working with github)
* name="github" This is the name for remote
Now that you understand the concept of repository, you can "fork" one and start making your
changes and keep it up to date with LineageOS source. For that, you need a Github Account.​
4. Repository Fork
In this example, i will fork Oneplus ONE device tree
1. Create Github Account
2. Go to https://github.com/LineageOS/android_device_oneplus_bacon and tap on Fork button. After that you can see that repository on you Github account
Image:
3. Now that you have "forked" one repository, you need to edit ~/working_dir/.repo/local_manifests/roomservice.xml and change the default location to your location on your github.[/SIZE]
Image:
This is the basic steps you need to understand how to use Github to keep your code saved and updated. On next section, i will tell you how use Git so you can work on your project and start to pick some cool commits from others projects.​

Hello ,
Thanks for your tutorial. It was very well explained.
I have a question in the step: "Prepare the device-specific code".
The last available branche of my device at https://github.com/LineageOS/android_device_samsung_treltexx/tree/cm-13.0, is the cm-13.0 version,
Should I tell which of the options on the device?
$ Source build / envsetup.sh
$ Breakfast "[COLOR =" Red] Samsung Galaxy Note 4 (Exynos) or treltexx [/ COLOR]
Another question: since the last branche is from cm-13.0, if I follow your tutorial, will it compile a, lineage 14.1 rom? Or CYanogenmod 13.0?
Thank you

Since your device tree doesn't have 14.1 branch you have to sync Lineage 13.0 branch
Code:
repo init -u https://github.com/LineageOS/android.git -b cm-13.0
After that you have to sync your especific device repos
Code:
$ source build/envsetup.sh
$ breakfast treltexx

Thanks for the great post! I have two questions to ask:
1. How to change LINEAGE_VERSION? Currently when performing brunch I've got
Code:
LINEAGE_VERSION=14.1-20170311-UNOFFICIAL-oneplus3
and I wish to change it to
Code:
LINEAGE_VERSION=14.1-20170311-HAZUKI-oneplus3
to distinguish my personal modified build.
2. When I wish to sync again to obtain latest commits, how far should I go back? Is performing "repo sync" and then "brunch oneplus3" already good enough? Do I need to perform "make clean" or something similar?
Thanks in advance!
I'm trying to build this for my galaxy s5 and I'm using that same guide to the letter and I'm just getting errors. And all those packages listed in op don't work either. I also get an error when extracting proprietary blobs. The extracting isn't the error it's that all the files aren't found in source code at all?!? I'm splitting bloody atoms trying to figure this crap out. Any help at all??

1. In order to add some code to your build, you have to get familiar with git/GitHub. I'm preparing my next chapter to talk about it
2. Yes, you have to "make clean" everytime before build

You have to show all your errors and all your steps in order to get help!
I'm using the exact same directions in the OP. No different order exactly the same order only for my specific device. The first pic is when I extract the proprietary blobs from the lineage ROM zip. The second pic is after trying to build it I get the ninja wrapper error 1 at the end. Oh and I'm running ubuntu 16.10 on VirtualBox. And my build environment was setup step by step off the android website

Why did you run: " ./extract-files.sh ~/original"
FSadino said:
* A relatively recent 64-bit computer (Linux, OS X, or Windows) with a reasonable amount of RAM and about 100 GB of free storage (more if you enable ccache or build for multiple devices). The less RAM you have, the longer the build will take (aim for 8 GB or more). Using SSDs results in considerably faster build times than traditional hard drives.

Can you tell me, where the space is nescessary in the file-sytem on a linux-PC?
Of course /home needs much space, as the build is done there, but where else?

It depends on which Linux distribution you install. Usually between 10Gb/15Gb should be enough for file system partition "/"

It is kubuntu 16.04.02, so this means all the hard disk space will be for /home filesystem, correct?
Another question, where is the space for the cache, for i can't see any parameter.
edit ok, looks like the cache is located at /home/..ccache, is there a possibility to move this location?
Could it be, that java 8 can be used for 13.0 also? I did not install java 7, but was able to build a working lineage 13.0.

You have to make root partition for system (/) with 10Gb/15Gb and home partition (/home) with the remaining disk space.

I have a question. I repo synced lineage 13. The build was successful but doesn't boot. I am building for Moto E surnia. I breakfast surnia it didn't ask for vendor files but built correctly. What could be wrong? The kernel log doesn't tell me too much. It's frustrating. All my previous builds booted up before.( I compiled DU for the surnia) Also use the same environment to build Twrp recoveries. I am downloading lineage 14 to try again. Maybe someone can point me in the right path please
Hi, I am building klte version of CrdroidAndroid ( a LineageOS based ROM) on a ubuntu 16.04 LTS VM.
I am getting the following error. I am not sure what to do here. I have been cleaning the build folder and ccache and trying to build. I keep ending at this error. Any help to solve this issue is greatly appreciated.

Building AOSP

I am trying to build AOSP. I have followed some instructions and the best are the instructions of Sony. But when I come to the point to clone the local_manifests, I need to have another file because I am trying to build it for the OnePlus One. I have found the AOSP-bacon repo on github where is a local_manifests to clone. So I have done that but when I try to sync the repo with the command 'repo sync' it gives this back:
[email protected]:~/android$ repo sync
fatal: remove-project element specifies non-existent project: platform/build
I have searched but could not find the answer what to do now. Can someone help me or say what I need to do to build AOSP?
You're cluttering your roomservice.xml with too much stuff. You only really need 3 things, device tree, vendor and kernel sources. You don't need to define the github tag since it should already have been defined in your default.xml located in .repo/manifests.

Having trouble compiling Oreo AOSP

Hi all,
I'm having trouble compiling the AOSP for Oreo. I've tried doing this both for the emulator and for bullhead.
I'm trying to build the AOSP (Oreo) for the Nexus 5x. I am building on Ubuntu 14.04.
I went to the AOSP requirements page (sorry, I don't have enough posts here to post links...) and installed all of the requirements. I even uninstalled my version of OpenJDK8 (161) in favor of the 45 version on the site. By using sudo update-alternatives --all, I made sure all of my java related commands point to this version of java 8.
I got the binary preview blobs from the Android device blobs webpage and untar'd/ran after getting the AOSP.
From the build numbers page I found the build for the nexus 5X is OPR6.170623.013, corresponding to branch android-8.0.0_r4.
So, I repo init -b android-8.0.0_r4, followed by a repo sync, followed by extracting my binary images (which placed them in vendor, as expected). Then I did a lunch, selecting aosp-bullhead-userdebug (option 25), and then make -j8.
After over an hour of building, the build fails (81 errors) on many of the java files with the following error.
"error: unmappable character encoding for UTF-8 // ? 2016 and later: Unicode, Inc. and others."
Does anyone know how I can resolve this build error?
