From the stack trace it seems that its giving me an OutOfMemoryError from the heap. The only class I found in here that related to ForgeGradle is ApplyFernFlowerTask which I'm guessing is the task that runs the decompiler. I'm not real sure what to do...

ForgeGradle for 1.8.8+ requires at least 2 GB of memory to decompile Minecraft. I believe this is due to Mojang's obfuscation process leaving generics intact instead of stripping them.

 

This tutorial explains how to give ForgeGradle more memory.

Thanks for the reply. I'm going to try this and see if it works.

Cool it worked thanks for help Choonster. I'm going to mark this as solved

 

Edit: Thanks for the link to mcforge documentation. I didn't know there was an official documentation for forge. Thanks again.
