"Prefer to run the dagger processor over that class instead" in Kotlin

I'm getting this note in the build whenever I do an inject into a kotlin class (btw, I have a mixed android project with both kotlin and java).

For example, after this gradle task: `compileStagingDebugJavaWithJavac` (StagingDebug is my build variant), I get this message:

> "Note: Generating a MembersInjector or Factory for com.packageNameXXX.CourseDiscoveryMapFragment. Prefer to run the dagger processor over that class instead."

My **CourseDiscoveryMapFragment** code can be seen here:

class CourseDiscoveryMapFragment : Fragment(){

@Inject
lateinit var presenter: CourseDiscoveryMapPresenter

lateinit var mapView: MapView

override fun onCreateView(inflater: LayoutInflater, container: ViewGroup?, savedInstanceState: Bundle?): View? {

val view = inflater.inflate(R.layout.fragment_discovery_map, container, false)

MapsInitializer.initialize(activity)

mapView = view.mapView
mapView.onCreate(savedInstanceState?.getBundle(BUNDLE_KEY_MAP_STATE))

(activity as BaseActivity)
.activityComponent.inject(this)
}

And my **ActivityComponent** is :

@ActivityScope
@Subcomponent(modules = ActivityModule.class)
public interface ActivityComponent {

void inject(BaseActivity baseActivity);

void inject(CourseDiscoveryMapFragment fragment);

//Exposed to sub-graphs.
Activity activity();
}

So, I'm having dagger component and modules written in Java, while having dagger injections in Kotlin.

Is this anything that I should be worried about?

Thank you.

I am afraid you can't. Why not write dependency modules in Kotlin?

To write dependency modules in java, you need to configure your Gradle script in this way:

> compile 'com.google.dagger:dagger:2.8'
> apt 'com.google.dagger:dagger-compiler:2.8'

But, to write dependency modules in Kotlin, you should configure your Gradle script in this way:

> compile 'com.google.dagger:dagger:2.8'
> kapt 'com.google.dagger:dagger-compiler:2.8'

dagger need the annotation processing tool to generate the dependency code during the compiling process. So I guess you just need to use the right APT(annotation processing tool) according to right language.
