Sorry to bug you, but when I call NBTInjector.inject() in my plugin's onEnable function, I'm getting an error with the generated classes:

I've looked into it and see where it's failing, but I haven't been able to track down any solution.

Here's my pom.xml if it's relevant:

You have to call it during onLoad, not onEnable

Oh my god I feel stupid now, thank you for the quick response!

I hate to bug you again, but I've switched it to onLoad as it should be, but I'm getting the same error as before (failing to inject random entities each time I start):
