Hello Everyone, I am facing an issue while compiling ai2 companion app.
The issue is java.lang.OutOfMemoryError: GC overhead limit exceeded

Build failed logs are below:

How I can resolve these issues?
Any solution to this?

Hello @Official_KunalMishra Here I see an issue

My guess : change your JAVA_OPTIONS , set them to -Xmx2048m instead of -Xmx1024m

There's a second flag in buildserver/build.xml childProcessRamMb that controls the amount of memory used for the dx process. By default it is 2 GB. You can try increasing it to a larger value to reduce the chances of an OOM error.

increase 1024m to 2048m and also make change in sources
