Posted March 27, 20169 yr 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!

March 27, 20169 yr 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 It's been superseded by 1.8.9. Please don't PM me to ask for help. Asking your question in a public thread preserves it for people who are having the same problem in the future.
March 27, 20169 yr Author 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.
