java.lang.AssertionError: Duplicate type name

[tamastimar]

Hi, after updating j2objc to any newer version than 2.2, I get the following error without changing anything else in the codebase:

Error Output:
  Exception in thread "main" java.lang.AssertionError: Duplicate type name: DopplRuntime

We use some libraries from the Doppl project, so DopplRuntime definetly comes from there.

My suspect from the stack trace is this change: 887f191.

Does that change anyhow alter the order or method of dependency resolution, that's why j2objc discovers DopplRuntime multiple times?

Any solution idea within the scope of j2objc as Doppl seems not to be updated anymore?

Thanks!
