Thanks for the quick answer ! Unless I am missing something I think I do ? My Java version is 8u256. Or are you talking about the JDK version ?

Hello everyone ! Firstly, I am very sorry if I am not in the right part of the forum, or if someone already had the same problem as me. I looked, but can't seem to understand what my problem is... So I come to you in hope of your enlightenment ! So, I am using Intellij, I successfully did the build.gradle, etc... Then I tried to compile and launch, forge loader opens and theeen... The game crashes. Here's the log : ---- Minecraft Crash Report ---- // Surprise! Haha. Well, this is awkward.
