Referencia no resuelta para Dagger 2 en Kotlin

Estoy tratando de usar un Dagger 2 en mi proyecto Android donde codigo en Kotlin. Tomé un ejemplo de Dagger 2 repo android-simple . He logrado configurar correctamente el proyecto en Android Studio usando un ejemplo de dagger-android-gradle-sample , contiene files gradle configurados correctamente.

Ahora comencé a cambiar las classs de java a kotlin. Así es como luce auto-convertido DemoApplication.java en 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) } } 

Las classs generadas por Dagger son visibles en Kotlin, pero se queja del signo ($) usado en el nombre de la class. ($) en Kotlin tiene un propósito especial, así que supongo que es por eso. Puedes notar que la auto-conversión envolvió el nombre de la class con el signo (`) para que el editor no se queje de él. Desafortunadamente, el comstackdor está fallando con:

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

También hay una exception si bash buildlo desde la Terminal:

¿Alguien sabe cómo solucionar este problema? Si no, tendré que mantener las classs usando Dagger_ * en java.
