New Modder Help with Crashing

[VeteranWarrior]

Today I decided I wanted to get into modding, so I did the first step in creating my workstation. I downloaded IntelliJ, changed the PATH variable to JDK, changed all the examplemod names, etc. but whenever I try to run Minecraft from IntelliJ, it crashes.

 

Any and all support is greatly appreciated!

Did you set up your decomp workspace, and create intellij runs?

This error happens when you setup your environment with Java 9+ and then run it with Java 8. If your JAVA_HOME is set to Java 8 now create a new workspace. If that doesn't work uninstall all Java 9+ then setup another workspace.

I thought I uninstalled all Java9+ stuff, how do I make sure I did? Whenever I type java -version in the Terminal it only shows Java 8. Also I'm a little daft could you tell me where and how to see what JAVA_HOME is set to?

Java is just another program on your computer, you uninstall it just like you do everything else.

Google it. It's different for each OS.

I did this, and now this is appearing:

 

 

Also sorry if this is annoying to you, I'm very new to all this and I'm an ex-Ubuntu user

Yes I think so, unless my problem was during these processes

 

I'm also getting this:

Error: Could not find or load main class net.minecraftforge.userdev.LaunchTesting

Process finished with exit code 1

Ok what is the problem? Have you ran those? runClient runs the Minecraft Client. runServer runs the Minecraft Dedicated Server, and runData I'm not a hundred percent on but I think it runs the Provider system for generating BlockStates and other json files.

Yes whenever I run runClient it gives me that error, though I did cd <file path> and gradlew genIntellijRuns
