I'm working on a mod that uses this mod as a dependency, but when I try using runData in my IDE the instance will crash due to a ResourceLocationException. I've tested it with runClient and runServer as well but I don't get the error then which leads me to believe it's only an issue with using runData.

Make sure your datagen run args has '--mod', your_mod_id, otherwise you datagen for all mods.

Yeah, I have that but it still doesn't work. I'll upload my build.gradle to paste bin for you to check. I also tried using the official maven repo as well thinking cursemaven was screwing something up but that didn't fix anything either.
