Hello,

 

I have been trying to update my forge version from 1.8 and i have only been getting exceptions.

 

I tried downloading a fresh dev kit and i still get this error:

 

This mapping 'snapshot_20151122' was designed for MC 1.8! Use at your own peril.

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.

 

Side note: Why are you using 1.8.8? It's been superseded by 1.8.9.

Thanks, I will give that a go. I did try using 1.8.9 but that didn't work so then I tried 1.8.8 to see if that would work.
