Unable to access inner class, @Shadow does not seem to support it

[brunogenovese]

This might simply be a matter of not finding the right documentation, if so I would greatly appreciate if you can point me to it.

Problem:

• Simply attempting to access an inner class while in a mixin, for example

• ModelLoader.ModelDefinition x = new ModelLoader.ModelDefinition(myUnbakedModelList, myValues);
  

• The compiler message is: "net.minecraft.client.render.model.ModelLoader.ModelDefinition' has private access in 'net.minecraft.client.render.model.ModelLoader"

Attempted solutions and their problems:

1. Add @shadow static class ModelDefinition; to the mixin:

• Compiler message: "Inner classes are only allowed if they are also @mixin classes"

2. Create a Mixin for the inner class:
   @Mixin(ModelLoader.ModelDefinition.class) public class ModelLoaderMixinModelDefinition { }
   -Get the same "private access" error on ModelDefinition. The error message in (1) seems to indicate that "there is a way" to make a mixin for an inner class but it is not clear what that is.

Conclusion:
A) If there is already mixin support for accessing inner classes, some documentation is necessary.
B) If there is no mixing support for accessing inner classes, it might be a good idea to add the functionality.

You can mixin to classes you're not allowed to access by passing the string name of the class:

@Mixin(targets = { "net.minecraft.client.render.model.ModelLoader$ModelDefinition" })
public class ModelDefinitionMixin {
}

However, depending on how much you need to access, there's a good chance you will still want to use an access transformer/widener to make the inner class public first. For example, you still can't declare any variables with that class as a type since you aren't supposed to have access to it.
