I feel stupid again, user error on this one. I assumed the "jar" task would also build, I guess I need extremely verbose descriptions of each task. Thank though this was driving me crazy

(forge-1.11.2-13.20.1.2393 in case this is a version specific issue) The issue I'm having is now that I feel my mod is finished and I make the jar file and add it to a live version of minecraft (exact same forge version, I made sure of it) I get all sorts of NoSuchMethodErrors like: Only Vanilla functions seem to throw errors, I can get the game to run just fine adding a bunch of null enchantments using the registry system, but the moment I call something non-forge the game crashes. In my eclipse environment the code runs just fine, it is only in a finished jar of the mod I am getting these issues. I tried both the "gradlew jar" command and also the built-in eclipse export function, both with the same errors. So my question is did I mess up with my project setup and how can I fix this? Edit: I know this is kinda hard to explain and debug, I'm just hoping someone else has ran into this exact issue before.
