SuperHarmony910

@Beethoven92 Thank you for that, couldn't figure it out! I'm new to building mods and since this is my first one, I just recopied it from the MDK. I hope I'll get back to modding very soon, ty!

Exit code 0 issue(fixed!) I am trying to develop my first mod for Minecraft, which includes adding a new block and item to the game, but after I have created ItemBase.java, RegistryHandler.java & a new texture using paint.net, every time I copy it to the mods folder (I don't test it via runClient, it's not compatible via JDK 14, which I use for Java projects and CMD gets mad if I replace it with JDK 1.8.0 in PATH) and run it via Minecraft Launcher, I will repeatedly get this issue: I also have a GitHub issue relating to this here: https://github.com/SuperHarmony910/modification-builder/issues/9, I would prefer if solutions were posted there but I am not too fussy on that.
