Compiling Bazel Java code...

There are my environment:
Platform:
Linux debian 3.16.0-4-686-pae #1 SMP Debian 3.16.7-ckt25-2 (2016-04-08) i686 GNU/Linux
java version:
java version "1.8.0_91"
Java(TM) SE Runtime Environment (build 1.8.0_91-b14)
Java HotSpot(TM) Server VM (build 25.91-b14, mixed mode)
java -XshowSettings:vm
VM settings:
Max. Heap Size (Estimated): 437.50M
Ergonomics Machine Class: server
Using VM: Java HotSpot(TM) Server VM

The javac's heap size is 256m in the Java Visual VM.
I had tried every way as I could.
Thanks very much!

I find the way to fix this problem:
vim scripts/bootstrap/compile.sh
find the "run "${JAVAC}" -classpath "${classpath}" -sourcepath "${sourcepath}"" and add
-J-Xms256m -J-Xmx384m
as
" run "${JAVAC}" -J-Xms256m -J-Xmx384m -classpath "${classpath}" -sourcepath "${sourcepath}""
and it works well.

Thanks, that's awesome!

Hi everyone!
The previous answer helped me in the begging of compilation, but in the very end I get the same again even with extra options. The error code:

ERROR: /home/iwi/bazel/src/main/java/com/google/devtools/build/lib/standalone/BUILD:5:1: Java compilation in rule '//src/main/java/com/google/devtools/build/lib/standalone:standalone' failed: Worker process sent response with exit code: 1. An exception has occurred in the compiler (9-internal). Please file a bug against the Java compiler via the Java bug reporting page (http://bugreport.java.com) after checking the Bug Database (http://bugs.java.com) for duplicates. Include your program and the following diagnostic in your report.

Hello,
I know this is an old post but I tried what @JaidenChiang did and still had a "system out of resources" message. @JaidenChiang still got it right! I only had to add this to his line edit: -J-Xms512m and it works now, the edited line becomes like:
run "${JAVAC}" -J-Xms256m -J-Xmx384m –J-Xms512m -classpath "${classpath}" -sourcepath "${sourcepath}
Hope this helps those who encountered something similar to what I had :)

Sorry to leave a comment on a closed issue and bother everyone, but with the commit 09222fa in place, it is now possible to set up an environment variable and insert extra javac options, like this:

env BAZEL_JAVAC_OPTS="-J-Xms384m -J-Xmx512m" bash ./compile.sh

If anyone is still stuck on this and stumbles upon this thread, here is the quick fix from my Stack Overflow answer here:

If bazel runs out of memory while building, and you see this error:

java.lang.OutOfMemoryError: Java heap space

...then do this:

1. Increase your RAM or your virtual memory swap file size, to emulate having more RAM (details on how to do this are below).
2. From now on, build with this bazel command, for example, to give Bazel more heap space (RAM) while building. In this case I am giving it 32GB maximum RAM:

   # Do this to give Bazel up to 32GB of RAM wile building
   time bazel --host_jvm_args=-Xmx32g build //...
   
   # ...instead of doing this
   time bazel build //...
