AndroidX Support Library classes cause binding failure

Versions: Dagger 2.16 Android Studio 3.2 Beta 1 Support Library: androidx.appcompat:appcompat:1.0.0-alpha3

When I use dagger.android.support.DaggerApplication as the base class for my Application, I receive this error upon compilation.

FAILURE: Build failed with an exception.

When I replace import dagger.android.support.DaggerApplication with import dagger.android.DaggerApplication, the error goes away but I am unable to use DaggerAppCompatActivity or DaggerFragment from the support libraries.

A minimal project to reproduce the issue is located here: magneticflux-/AndroidXDagger2Bug, simply try to use the support library features and it will fail to compile.

If you’re using the support application, you need AndroidInjectionSupportModule

That makes sense, thanks for explaining it; I don’t have much experience with the advanced features of Dagger 2.
