Post the new crashlog, or if it is the same, then you didn't actually recompile with java 8

(Im just starting)

Get what, the log? It will be in the logs folder of either the minecraft game directory, or if you're running from the IDE, it will be in the run folder in your project folder.

I would suggest posting the new logs. It is possible that Java is no longer the problem if you have removed other versions. The logs will tell us what is actually going on.

That's a newer log, but the errors are exactly the same, so I would say the original suggestion is still true.

I honestly couldn't tell you, I've never run into this issue, hopefully someone that knows will see it and have some advice!

Ran into this exact same issue. Uninstalled eclipse/my jdk/even tried things like deleting .minecraft and reinstalling forge.

What I noticed is that whenever I ran ./gradlew genEclipseRuns it was building ~very~ fast, so I downloaded another version of the sourceForge mdk and rebuilt and it worked.

I went with mdk 31.1.30, because my second guess was that this might be a new uncaught bug.

But my guess is that it just has to be a different version, so maybe 31.1.48 or something.

My guess is there is something being cached by gradle for that initial eclipse build from the newer java version.

Maybe a faster way to fix this can be done by looking into ...\.gradle\caches and deleting forge related caches.

Ok i'll try it, gradlew was building super fast for me as well so it could be the same problem.

Thanks
