I'm not using the export jar functionality, I'm using the build configuration like the runClient and runServer configuration (where you press play and debug). Its a gradle task with the name 'build' but apparently it doesn't work correctly.
Nevermind, it is an obfuscation problem after all. Somehow my Intellij configuration has as task 'build' but it doesnt obfuscate. So I have to go into the terminal and type 'gradlew build' from there.
I've updated my Effortless Building mod today. To my surprise, the Twitch version gives a NoSuchMethodError error. The build I made and tested locally (using 'gradlew build') works fine, even in the same Twitch profile. But when I download the public version from curseforge.com it gives an error.

I'm just very confused at this point. Any idea what is going on?
