No, it works. There was a thing in my build.gradle that I removed, it built correctly, and minecraft launches outside of eclipse with the mod fully functional.
Sorry, that was for a thing I was working on after it wouldn't compile. I was trying to make it so that if you mine it with one level of pickaxe, it would return coal, but if you mined it with another, it would return jet. And I was struggling to find out how to do that, that was just a placeholder. It still gives me a similar error.
It's giving me the message "Build failed with an exception" and "could not copy file 'src\main\resources\mcmod.info' to 'build\resources\main\mcmod.info'.
