Exception in thread “main” Java Lang. outofmemoryerror: GC overhead limit exceeded in GWT application

I am developing applications using GWT and gae When I try to rebuild it or create an artifact, I get a lot of errors as shown in the figure below

I searched Google and stack overflow, and I got some answers, but not my specific question
