I recently started using dagger-2 with kotlin. Unfortunately, I solved the problem with sumbcomponants, and I had problems understanding why I get this gradle error:
...NetComponent (unscoped) may not reference scoped bindings: @dagger.Subcomponent(modules = {com.example.kremik.cryptodroid.di.module.NetModule.class}) @Singleton @Provides com.example.kremik.cryptodroid.data.remote.CMCService com.example.kremik.cryptodroid.di.module.NetModule.providesCMCService(retrofit2.Retrofit) @Singleton @Provides retrofit2.Retrofit com.example.kremik.cryptodroid.di.module.NetModule.providesRetrofit() @org.jetbrains.annotations.NotNull @Singleton @Provides com.example.kremik.cryptodroid.data.service.CurrencyDataPresenter com.example.kremik.cryptodroid.di.module.NetModule.providesCurrencyDataPresenter(com.example.kremik.cryptodroid.data.local.CurrenciesProvider, com.example.kremik.cryptodroid.ui.LivePrices.LivePricesPresenter)

NetComponent:
@Subcomponent(modules = arrayOf(NetModule::class)) interface NetComponent { fun inject(service: CurrencyDownloaderService) }
Does anyone know what the problem is?
