Dagger 2 Singleton Component Depend On Singleton : <p>I've got a strange problem here, and I'm not quite sure why what I'm doing isn't allowed. I've got the following modules:</p>

<pre><code>@Module
public final class AppModule {
  private Context mContext;

  @Provides
  @Singleton
  @AppContext
  public Context provideContext() { return mContext; }
}

@Module
public final class NetModule {
  @Provides
  @Singleton
  public OkHttpClient provideOkHttp() {
    return new OkHttpClient.Builder().build();
  }
}
</code></pre>

<p>For various reasons, I don't want to have these two modules in the same component (basically due to my project structure). So I tried to create the following components:</p>

<pre><code>@Singleton
@Component(modules = AppModule.class)
public interface AppComponent {
  @AppContext Context appContext();
}

@Singleton
@Component(dependencies = AppComponent.class, modules = NetModule.class)
public interface NetComponent {
  Retrofit retrofit();
}
</code></pre>

<p>But when I try to compile this, I get the following error message:</p>

<p><code>Error:(12, 1) error: This @Singleton component cannot depend on scoped components:
@Singleton com.myapp.service.dagger.AppComponent</code></p>

<p>I understand why depending on <em>different</em> scopes would be bad and disallowed. But why is Singleton depends-on Singleton not allowed? This feels like it should work, since all I'm doing is declaring sibling components. What am I missing?</p>
