Nierozwiązane odniesienie dla Dagger 2 w Kotlin

Question

Próbuję użyć Dagger 2 w moim projekcie Android, gdzie koduję w Kotlin. Wziąłem przykład z Dagger 2 repo android-simple. Udało mi się poprawnie skonfigurować projekt w Android Studio na przykładzie z dagger-android-gradle-sample, zawiera on poprawnie skonfigurowane pliki gradle.

Teraz zacząłem zmieniać klasy java na kotlin. W ten sposób automatycznie konwertowane DemoApplication.java wygląda w Kotlin:

public class DemoApplication : Application() { 

    Singleton 
    Component(modules = array(javaClass<AndroidModule>())) 
    trait ApplicationComponent { 
     public fun inject(application: DemoApplication) 
     public fun inject(homeActivity: HomeActivity) 
     public fun inject(demoActivity: DemoActivity) 
    } 

    public var component: ApplicationComponent? = null 

    override fun onCreate() { 
     super.onCreate() 
     component = `Dagger_DemoApplication$ApplicationComponent`.builder().androidModule(AndroidModule(this)).build() 
     component!!.inject(this) 
    } 
} 

Dagger wygenerowane klasy są widoczne w Kotlin, ale skarży się na ($) znak używany w nazwie klasy. ($) w Kotlin ma specjalny cel, więc myślę, że to dlatego. Możesz zauważyć, że auto-konwersja zawijała nazwę klasy znakiem (`), więc redaktor nie narzeka na nią. Niestety kompilator nie udaje się:

Error:(32, 21) Unresolved reference: `Dagger_DemoApplication$ApplicationComponent` 

:app:compileDebugKotlin FAILED 

Jest też wyjątek, gdy próbuję zbudować go od terminalu:

Czy ktoś wie jak rozwiązać ten problem? Jeśli nie, będę musiał prowadzić zajęcia przy pomocy Dagger_ * w Javie.

Answer 1

Możesz go rozwiązać, czekając! Zobacz https://github.com/google/dagger/issues/58.

Symbol $ jest usuwany ze wszystkich wygenerowanych kodów przed pierwszym wydaniem (i mam nadzieję, że raczej wcześniej niż później).

Dodatkowo, zgłosiłbym błąd w Jetbrains dotyczący zachowania, ponieważ $ jest doskonale poprawną postacią, która pojawia się w nazwie klasy.
