Dagger 2: @Component.Builder is missing setters for required modules or components: [appi.example.com.dagger.AppModule]`

Question

I\'m configuring the new Dagger Android module but I got this error Here\'s my Component:

@AppScope
@Component(modules = {AppModule.class, NetModule.class})
         


        

Answer 1

Remove the below code from the AppModule.class and rebuild the project

    @Provides
    @Singleton
    Application provideContext(SomeApplication application) {
        return application;
    }

Answer 2

I think this provides a somewhat clearer explanation on the use of @BindsInstance and removal of @Provides Application, Dagger 2 Component Builder:

@BindsInstance What?

Here’s the definition :

Marks a method on a component builder or subcomponent builder that allows an instance to be bound to some type within the component. — source

WHAAT? I don’t understand it either

Answer 3

In my case I was using an object Module, so I had to annotate provider method with @JvmStatic

@Module
object GsonModule {

    @JvmStatic
    @Singleton
    @Provides
    fun provideGson() = Gson()

}
