Hello, I have made a mod in eclipse and it works just fine with no errors. But when I export it as a java file and try to run it in regular minecraft, I get a crash. I have no clue why this would happen.

My crash log:

How did you compile it?

What do you mean by "exporting as a jar file" ? Just run gradlew build, and copy the JAR file under build/libs in your mods folder.

No I did file -> export, in eclipse

That doesn't work for Forge mods, you need to run the gradlew build command.

It won't work. Do what I said and it should work.
