Importing cm apps to intellij - Android Q&A, Help & Troubleshooting

Hi guys don't know if this is the right thread to post my issue
"I want to import apps of the cm source code to edit them in the intillij (Android Studio)"
After successfully compiling the cm source code i decided to edit some apps
but when i tried this command "make idegen && development/tools/idegen/idegen.sh" from the cm_wiki on how to import apps to intillij it fails
the followed instruction :
croot
make idegen && development/tools/idegen/idegen.sh
Open Intellij
Click Open an existing Project
Navigate to ~/android/system
Choose android.ipr
Finish
Note: Should you be developing multiple branches of CyanogenMod, consider an alternative naming scheme for the .ipr & ipl files. this should be done before #2 above.
Rename .ipr: mv android.ipr CM12.ipr
Link .ipl: mv android.ipl CM12.ipl && ln -s CM12.ipl android.ipl
here is my output :
Code:
[email protected]:~/android/system$ make idegen && development/tools/idegen/idegen.sh

What seems to work for me
cd <root of CM>
source build/envsetup.sh
croot
export PATH=<java1.7+>/bin:${PATH}
make idegen
export ANDROID_HOST_OUT=out/host/
development/tools/idegen/idegen.sh
