I’m using `kotlin-inject` + `kotlin-inject-anvil` ...

# kotlin-inject

[Marko Novaković]

I’m using kotlin-inject + kotlin-inject-anvil and my component is interface ApplicationComponent : ApplicationComponentMerged which is fine. ApplicationComponentMerged is generated but ApplicationComponent can’t access things provided by components that ApplicationComponentMerged extends/inherits

[Marko Novaković]

I’m using Circuit code generation and the hierarchy is:

@Origin(value = CameraPresenterFactory::class)
public interface CameraPresenterFactory {
  @Provides
  @IntoSet
  public
      fun provideCameraPresenterFactoryFactoryMultibinding(cameraPresenterFactory: CameraPresenterFactory):
      Presenter.Factory = cameraPresenterFactory
}
-----------------
public interface ApplicationComponentMerged :
    TechMappsSevenwondersduelscoringCameraCameraPresenterFactory
---------------
public class InjectApplicationComponent : ApplicationComponent,

but there is an error where provideCameraPresenterFactoryFactoryMultibinding which exists inside CameraPresenterFactory
gives Unresolved reference:

public class InjectApplicationComponent : ApplicationComponent, ScopedComponent {
  override val _scoped: LazyMap = LazyMap()

  override val circuit: Circuit
    get() = circuit(
      presenterFactories = setOf(
        provideCameraPresenterFactoryFactoryMultibinding(
          cameraPresenterFactory = CameraPresenterFactory()
        )
      ),
      uiFactories = setOf(
        provideCameraUiFactoryFactoryMultibinding(
          cameraUiFactory = CameraUiFactory()
        )
      )
    )
}

Any chance that you misuse Gradle api vs implementation dependencies?

[Marko Novaković]

tried both, neither works

[ralf]

What's the exact error message?

[Josh Feinberg]

i get similar

e: file:///.../build/generated/ksp/jvm/jvmMain/kotlin/com/joshafeinberg/common/InjectAppComponent.kt:266:9 Unresolved reference 'provideAddTransactionPresenterFactoryFactoryMultibinding'.

however, in the build folder I do have

@Origin(value = AddTransactionPresenterFactory::class)
public interface
    ComJoshafeinbergCommonFeaturesAddtransactionAddTransactionPresenterFactory {
  @Provides
  @IntoSet
  public
      fun provideAddTransactionPresenterFactoryFactoryMultibinding(addTransactionPresenterFactory: AddTransactionPresenterFactory):
      Presenter.Factory = addTransactionPresenterFactory
}

i'm kind of wondering, and not sure if you have the same problem Marko, if theres something wrong with my gradle setup as I'm getting the IDE a warning of Unresolved reference: AppComponentMerged even though it compiles

[ralf]

This is strange. Not sure if this is Circuit related (maybe @Zac Sweers has an idea), a dependency issue (but then I’d expect an issue with the class and not the function), Kotlin 2.0 or any other reason.

I assume this happens in a multi-module setup. A sample would make this a lot easier 😕

[Zac Sweers]

I saw a similar error here: https://kotlinlang.slack.com/archives/C0255B8KX7W/p1726371615948419, but not in jvmMain

[ralf]

Is it this issue? https://github.com/amzn/kotlin-inject-anvil/issues/20

[Marko Novaković]

I’m getting same error as Josh, and my error happens inside androidMain codegen directory.

[Josh Feinberg]

i've ended up with a really weird fix for this, still trying to make a small reproducible sample though to file the bug

i have my AppComponent defined like this

@AppScope
@Component
@MergeComponent
internal abstract class AppComponent(...) : AppComponentMerged2

AppComponentMerged2 is kind of where the magic worked. this is just expect interface AppComponentMerged2 and then in all my sourcesets i have an actual defined as actual interface AppComponentMerged2: AppComponentMerged

So this does seem to be a very similar error to the one Chris reported. this workaround works for now though

[Zac Sweers]

hmm, that doesn’t seem to resolve the issue I linked above, but maybe that’s further confirmation that my error is a different one and specific to iosMain source sets

[Marko Novaković]

what about java.lang.IllegalStateException: Storage for [.../build/kspCaches/android/androidDebug/symbolLookups/id-to-file.tab] is already registered
with same setup?

[Zac Sweers]

that looks like an unrelated KSP ephemeral IC state issue
