Regression in 2.3.7 with generic assisted factories

[ZacSweers]

we have a base interface for our factories that looks like this

interface AssistedWorkerFactory<T : ListenableWorker> {
  fun create(context: Context, params: WorkerParameters): T
}

with 2.3.7, this now results in this compilation exception

e: com.squareup.anvil.compiler.api.AnvilCompilationException: Back-end (JVM) Internal error: Invalid return type: slack.workmanager.workerfactory.AssistedWorkerFactory.create. An assisted factory's abstract method must return a type with an @AssistedInject-annotated constructor.
File being compiled: (17,3) in /mnt/buildkite-agent/builds/mbr-buildkite-agent-android-iad-ju4p-1/slack/android-pull-request/services/work-manager/src/main/kotlin/slack/workmanager/workerfactory/AssistedWorkerFactory.kt
 
	at com.squareup.anvil.compiler.codegen.dagger.AssistedFactoryGenerator$AssistedFactoryFunction$Companion$toAssistedFactoryFunction$returnTypeLazy$2.invoke(AssistedFactoryGenerator.kt:313)

I think this is an issue with it not properly reading the generic type. As an example, this is what we are doing

class FlushPendingExposuresWork @AssistedInject constructor(
  @Assisted appContext: Context,
  @Assisted params: WorkerParameters,
  // ...
) : CoroutineWorker(appContext, params) {

  override suspend fun doWork(): Result {
    // ...
  }

  @AssistedFactory
  interface Factory : AssistedWorkerFactory<FlushPendingExposuresWork>
}

🤦

Thanks for the report, and sorry for the bug. I'll look into it now.

The fun part is that by supporting PSI, there are now two scenarios where it can fail.

Thanks @RBusarow
