I've tried multiple time to setup a forge workspace, tried multiple versions everytime I try run the "./gradlew genIntellijRuns" command I get this error. I tried doing it on a different IDE I ran this command on windows cmd and with a batch file "gradlew genEclipseRuns --refresh-dependencies". Please be coherent in your reply cause I probably won't understand what you're trying to say cause I'm very new to this.
