Error happens when I try to compile Android source code(Sourcecode-version: 6.0.1; RAM: 6G; host system: ubuntu 14.04),log is below:

Anyone can tell me why the compiling failed?

Best Answer

I had the same problem. So I've tried to set JACK_SERVER_VM_ARGUMENTS to include -Xmx=4g, but when building again the log output showed that this was not included in the startup. I don't know why, it seems like the env vars do not get passed to the build script correctly.

Solution

Before starting a clean android build set the JACK_SERVER_VM_ARGUMENTS to include -Xmx=4g, then stop and start the jack server manually. Given you're in the main source tree of AOSP run the following:

export JACK_SERVER_VM_ARGUMENTS="-Dfile.encoding=UTF-8 -XX:+TieredCompilation -Xmx4g"
./prebuilts/sdk/tools/jack-admin kill-server
./prebuilts/sdk/tools/jack-admin start-server

for cm you can use

export JACK_SERVER_VM_ARGUMENTS="-Dfile.encoding=UTF-8 -XX:+TieredCompilation -Xmx4g"
jack-admin kill-server && jack-admin start-server

This resolved the issue for me.
