A way to use Mixins.addConfiguration()/Alternative to?

Description

In my project, I use Mixins.addConfiguration() to dynamically register mixin configs. The problem is that I have to rely on IExtension which has to be added using MixinInternals.registerExtension() from MixinExtras. This is very not stable and also breaks most threaded operations due to a class loading deadlock.

I'm wondering if there's a proper/better way to do this at runtime? I tried preLaunch, which works fine, until some mod loads a Minecraft class. IMixinConfigPlugin also has a classloading deadlock and using addConfiguration here crashes the game with ConcurrentModificationException.

I also thought about adding configs at compile time, but that comes with its own set of problems.

Is it just impossible to do cleanly?

Calling Mixins.addConfiguration from preLaunch is the correct approach. Any mod that loads minecraft classes in preLaunch is broken.
On another note you should absolutely not touch anything internal from MixinExtras, at all. It can change at any time.

Hmm, guess I'll have to retry preLaunch. Thank you.

It can change at any time.

I know, it's just that the method was already there when I was testing extensions. 😅
