@ContributesAndroidInjector: No injector factory bound for Class

See original GitHub issue

Dagger 2.11-rc2 Android Studio 2.4 preview7 classpath ‘com.android.tools.build:gradle:2.4.0-alpha7’ compileOptions { sourceCompatibility JavaVersion.VERSION_1_8 targetCompatibility JavaVersion.VERSION_1_8 }

When using @ContributesAndroidInjector, I get a runtime exception:

could somebody explain to me what was wrong here, and how to fix this issue? I’m trying to use the dagger in a Gradle multi-module project and getting the same exception

I see. That makes sense. Thanks! However, it is not immediately clear that ContributesAndroidInjector uses a map which prevents Dagger from promising to generate compile-time errors if something is amiss in this case.
