Auto-Dagger2 | Annotation processor on top of Dagger | Build Tool library

I'm trying to create an annotation processor which will process my MVP views (fragments) to auto-generated Subcomponents (similar to https://github.com/lukaspili/Auto-Dagger2, but for the new Dagger 2.10 android injectors)

So far, I've been able to generate appropriate files, but there is a strange error message when compiling generated components

Error:(22, 58) error: @dagger.android.support.FragmentKey methods should bind dagger.android.AndroidInjector.Factory, not dagger.android.AndroidInjector.Factory. See google.github.io/dagger/android

The structure of Factory module and Subcomponent files should be correct, because as soon as I copy-paste the generated classes and create a regular classes (both Factory module and Subcomponent) and use real classes instead of generated ones, the message is no longer shown and compilation succeeds

It seems like the problem lies in AndroidMapKeyValidator (link), where !MoreTypes.equivalence().equivalent(returnType, intendedReturnType) call apparently fails, but I don't have much of an experience debugging annotation processors, so I don't know why precisely...

Can maybe anyone help where to search for the problem? Thanks

FYI: MyFragment does extend android.support.v4.app.Fragment

Generated Factory @Module public interface BuildersModule { @Binds @IntoMap @FragmentKey(MyFragment.class) abstract AndroidInjector.Factory factory(MySubcomponent.Builder builder); }

Generated subcomponent @Subcomponent(modules = MyModule.class) public interface MySubcomponent extends AndroidInjector { MyPresenter presenter(); @Subcomponent.Builder abstract class Builder extends AndroidInjector.Builder {} }
