Android source code compile error: "Try increasing heap size with java option '-Xmx<size>'"
Solution 1
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.
Solution 2
The current way to set Xmx for jack is:
export JACK_SERVER_VM_ARGUMENTS="-Dfile.encoding=UTF-8 -XX:+TieredCompilation -Xmx4096m"
out/host/linux-x86/bin/jack-admin kill-server
out/host/linux-x86/bin/jack-admin start-server

I also had this problem after updating to 6.0 My computer is an i7 laptop with 8GB of ram. It worked fine with v5.x and below.
The reason is not enough memory as the error message states. In the v6.x build, more Jack is used. In my case, reducing the number of Jacks to 1 resolved the issue.
I can now continue compiling with 8GB of ram.
$HOME/.jack-server/config.properties
jack.server.max-service=1

Solution 4
Android build (tested with 7.1.2) uses its own, private version of Jack (there could be a Jack toolchain installed elsewhere on the system), so you have to use Android-specific variables.
From https://android.googlesource.com/platform/prebuilts/sdk/+/master/tools/README-jack-server.md:
(search for "If you experience Jack compilations failing on Out of memory error.:")
To summarize:
$ # Stop the Jack server
$ jack-admin stop-server
$ # apply the new setting
$ export ANDROID_JACK_VM_ARGS="-Xmx2g -Dfile.encoding=UTF-8 -XX:+TieredCompilation"
$ Finally, restart the build (do not manually start the Jack server!)
$ m # or any other build command
The build system should pick up the change and output the line:
Environment variable ANDROID_JACK_VM_ARGS was set, regenerating...
or (after a subsequent change):
Environment variable ANDROID_JACK_VM_ARGS was modified (-Xmx2g -Dfile.encoding=UTF-8 -XX:+TieredCompilation => -Xmx4g -Dfile.encoding=UTF-8 -XX:+TieredCompilation), regenerating...
Solution 5
I found this article: Building AOSP 7.x Nougat with only 8 GiB RAM
on an 8 GiB machine, Max Heap size is less than 2 GiB:
$ java -XshowSettings 2>&1 | grep Heap
Max. Heap Size (Estimated): 1.71G
The solution
Once I understood the problem, it was just a question of changing the default heap size when jack-server is launched. To fix it, you need to edit
~/.jack-settings, and add this line
JACK_SERVER_VM_ARGUMENTS="-Dfile.encoding=UTF-8 -XX:+TieredCompilation -Xmx4096m"
Then, restart jack-server – otherwise if it is running in the background it will continue to use the old Xmx value:
$ prebuilts/sdk/tools/jack-admin kill-server
$ prebuilts/sdk/tools/jack-admin start-server
Launching Jack server java -XX:MaxJavaStackTraceDepth=-1 -Djava.io.tmpdir=/tmp -Dfile.encoding=UTF-8 -XX:+TieredCompilation -Xmx4096m
-cp /home/chris/.jack-server/launcher.jar com.android.jack.launcher.ServerLauncher
