[1.20.6] NullPointerException in Forge: FMLJavaModLoadingContext.get() is null #68

Closed alnyan closed 4 months ago

alnyan commented 4 months ago

Forge version: 50.1.0 Registrate version: MC1.20-1.3.11

I'm having an issue trying to get Registrate working with my mod. I've added all the gradle stuff as described in the README.md, with appropriate version for 1.20. I use a lazy Registrate provider inside my @Mod class. Everything works okay until any of my classes with block/item registrations get loaded, at which point a NullPointerException gets thrown, for example, I get this problem when running runData gradle task and my data provider accesses some block inside MyModBlocks class (which causes it to load and throws an error, I presume).

I might be missing something or my Forge mod is misconfigured, but before switching to Registrate, I used RegisterEvent from ModEventBus to handle my registrations, which worked fine.

Here's an example log of the crash:

Okay, my bad, I failed to check if the library supports 1.20.6 first
