But (as far as I know) I already had Oracle Java JDK 16.0.1...

I suppose Oracle Java JDK 17.0.2 will work.

I was trying to create a new project in IntelliJ Idea when this error appeared: Could not find net.minecraftforge:forge:1.16.5-36.2.26_mapped_official_1.16.5 Somebody know whats wrong? This is the log: (Btw. I am quite new so I might have missed a simple mistake.)
