I'm configuring the new Dagger Android module but I got this error Here's my Component:

@AppScope
@Component(modules = {AppModule.class, NetModule.class})
public interface AppComponent {

  @Component.Builder
  interface Builder {
    @BindsInstance
    Builder application(ExampleApplication application);

    @BindsInstance
    Builder appModule(AppModule appModule);

    @BindsInstance
    Builder netModule(NetModule netModule);

    AppComponent build();
  }

  void inject(ExampleApplication __); 
...

Which I build like this in my Application

appComponent = DaggerAppComponent
      .builder()
      .application(this)
      .appModule(new AppModule(this))
      .netModule(new NetModule())
      .build()
      .inject(this);

But I still receive the error

Error:(20, 3) error: @Component.Builder is missing setters for required modules or components: [app.example.com.dagger.AppModule]

According to the documentation that should be right, What am I missing?

For example, this could be a valid Component with a Builder:

@Component(modules = {BackendModule.class, FrontendModule.class})
interface MyComponent {
  MyWidget myWidget();

  @Component.Builder
  interface Builder {
    MyComponent build();
    Builder backendModule(BackendModule bm);
    Builder frontendModule(FrontendModule fm);
  }
}

Remove the below code from the AppModule.class and rebuild the project

    @Provides
    @Singleton
    Application provideContext(SomeApplication application) {
        return application;
    }
