Read your errors.

 

Also, without your code, we can do fuckall to help you.

I know, its that specific problem I am trying to solve. Could it have something to do with gradle? I can run the code fine in IntelliJ but when I build a jar is when i get the aformentioned crash report.

Your code is trying to load a Kotlin class, but Minecraft/Forge don't ship with the Kotlin library. As with any other library, you'll either need to have users install it themselves or embed the library in your mod's JAR and have Forge extract it.
