Quote from Captain_Admiral

I think it's just a problem with how eclipse launches it due to how gradle has set up the newest version of forge, and not something that's easily fixable as of yet. Not sure if this is still up to date advice though.



I would recommend simply opening a command window in the folder with your gradle.bat and using "gradlew runClient" for now. Just until they fix it
