I was testing new feature of dagger: Android module. And I am not able to compile the code when I use @ContributesAndroidInjector
I am always getting following error:

Error:(12, 8) error: dagger.internal.codegen.ComponentProcessor was unable to process this interface because not all of its dependencies could be resolved. Check for compilation errors or a circular dependency with generated code.

I tried to implement my components like here, but still I got the error.

Here is the smallest example:

@PerApplication

@Component(modules = {AndroidInjectionModule.class, LoginBindingModule.class})

public interface ApplicationComponent {

    void inject(ExampleApplication application);

}



@Module

public abstract class LoginBindingModule {

    @ContributesAndroidInjector

    abstract LoginActivity contributeYourActivityInjector();

}



public class LoginActivity extends Activity {



    @Inject

    LoginPresenter loginPresenter;



    @Override

    protected void onCreate(@Nullable Bundle savedInstanceState) {

        AndroidInjection.inject(this);

        super.onCreate(savedInstanceState);

    }

}



public class LoginPresenter {



    @Inject

    public LoginPresenter() {



    }

}

If I remove LoginBindingModule from ApplicationComponent the app would be build, but would fail with runtime exception:

java.lang.IllegalArgumentException: No injector factory bound for Class

project setup:

gradle 3.3

buildToolsVersion "25.0.2"

dagger 2.11

Adding annotationProcessor com.google.dagger:dagger-android-processor:2.11 to your gradle file will resolve your problem.

In my case SomeModule class contained unnecessary lines:

@ContributesAndroidInjector

internal abstract fun fragmentInjector(): SomeFragment

For Kotlin, instead of

annotationProcessor com.google.dagger:dagger-android-processor:2.11

use

kapt com.google.dagger:dagger-android-processor:2.11

if none of the suggested solutions works, just check if you have forgot to add @Provides annotations to any of the dependencies, this was the issue in my case
