Dagger2使用中添加自定义Scope@AcvityScope 后报错AppComponent (unscoped) may not reference scoped bindings：

大四狗写毕设，遇到一个关于dagger2中 @scope的使用问题：

Dagger2使用中添加自定义Scope@AcvityScope 后报错
AppComponent (unscoped) may not reference scoped bindings：

AppComponent 及 相关module如下：

@Component(modules = {
        AndroidSupportInjectionModule.class,
        NeedInjectModules.class,
        DisposableModule.class
        })
public interface AppComponent extends AndroidInjector<MyApplication> {

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

        AppComponent build();
    }

}

@Module
public abstract class NeedInjectModules {

//    @ActivityScope
    @ContributesAndroidInjector
    abstract MainActivity injectMainActivity();
}

@Module(includes = ApiModule.class)
public abstract class DisposableModule {

//    @ActivityScope
    @Binds
    abstract BasePresenter bindDisposeblePresneter(DisposablePresenter disposablePresenter);

    }

@Module(includes = NetModule.class)
public class ApiModule {

//    @ActivityScope
    @Provides
    static ApiService provideApi(Retrofit retrofit) {
        return retrofit.create(ApiService.class);
    }
}

@Module
public class NetModule {

//    @ActivityScope
    @Provides
    Retrofit provideRetrofit() {
        return NetMgr.getInstance().getDefaultRetrofit();
    }

}

不加@ActivityScope完美运行,添加之后就出错. 求大佬们帮忙看看!!!

把@ActivityScope放在 AppComponent 的上面

@ActivityScope
@Module
public class AppComponent  {
