IntelliJ IDEA; Error: Could not create the Java Virtual Machine.

[ShadowProgrammer]

So, I'm new to modding Minecraft, but not coding in Java. I downloaded the forge mdk 1.18.2-40.1.0. I ran genIntellliJRuns, and it builds just fine, but when I run runClient, it gives me this error:

Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.
Unrecognized option: -p

I am using:

• jdk-8.0.332.9 from Eclipse Adoptium
• Windows 11
• IntelliJ Community Version 2021.2, 64 Bit

Please help.

Okay, so I installed Java 17 (jdk 17.0.3_7), and now I get two different error messages (FOLDER is just a stand-in for my directory):

Caused by: java.io.IOException: Invalid paths argument, contained no existing paths: [D:\FOLDER\ModTest\build\resources\main, D:\FOLDER\ModTest\build\classes\java\main]

AND

Execution failed for task ':runClient'.
> Process 'command 'C:\Users\USER\.gradle\jdks\adoptium-17-x64-hotspot-windows\bin\java.exe'' finished with non-zero exit value 1

What's happening?

EDIT: I moved this to a different forum post.
