first minecraft client i pasted, just were training my java skills for like 2 months and learning shit on this project. client is fully shit but better than the original trollgod i used as a base i guess, anyways nobody will use this so it doesnt matter.
to build use gradlew setupDecompWorkspace gradlew build
then go build/libs and there youll see the jar thingy
or just download the release if im not being lazy to build and publish it myself
