I am developing an application with GWT and GAE. When I try to rebuild it or create an artifact I get a lot of errors shown below in the picture.
I searched google and Stack Overflow and I got some answers but not to my particular problem.
From what I understand I get the error because my garbage collector consumes a lot of memory.
here is the main error Exception in thread "main" java.lang.OutOfMemoryError: GC overhead limit exceeded.
616
The "java. lang. OutOfMemoryError: GC overhead limit exceeded" error indicates that the NameNode heap size is insufficient for the amount of HDFS data in the cluster. Increase the heap size to prevent out-of-memory exceptions.
GC Overhead Limit Exceeded ErrorIt's thrown by the JVM when it encounters a problem related to utilizing resources. More specifically, the error occurs when the JVM spent too much time performing Garbage Collection and was only able to reclaim very little heap space.
OK, I fixed the problem. just increase the memory that the virtual machine needs to compile the project. Previously it was 128 and now I change it be 512. as my project grown it needed more memory to compile the classes of the project.Here is how to do that in Injtellj IDEA. right click on the project module -> open module settings -> Modules -> GWT -> compiler maximum heap size (Mb) -> changed to 512.
NOTE: In Ideal Intellij 12+ The project settings is in : File -> Project Structure OR Ctrl+Alrt+Shitf+S
