LazyClassKey not supported when using Dagger 2.53

[bddckr]

Using Anvil 2.5.0 with Dagger version 2.52 I have no issues. But updating Dagger to 2.53 (and doing no other changes to the project) gives issues when @LazyClassKey is used:

/something/build/generated/source/kapt/debugAndroidTest/something/DaggerSomethingComponent.java:41: error: cannot find symbol
import something.SomethingElse_Module_ProvideType_LazyMapKey;
                                       ^
  symbol:   class SomethingElse_Module_ProvideType_LazyMapKey

The SomethingElse_Module is generated by my own code generator via Anvil.

// Generated by Anvil.
// https://github.com/square/anvil
@file:Suppress(
  "DEPRECATION",
  "OPT_IN_USAGE",
  "OPT_IN_USAGE_ERROR",
)

package something

import com.squareup.anvil.annotations.ContributesTo
import dagger.Module
import dagger.Provides
import dagger.multibindings.IntoMap
import dagger.multibindings.IntoSet
import dagger.multibindings.LazyClassKey
import dagger.multibindings.StringKey
import kotlin.String
import kotlin.Suppress
import kotlinx.serialization.modules.SerializersModule
import kotlinx.serialization.modules.polymorphic
import kotlinx.serialization.modules.subclass

@Module
@ContributesTo(AppScope::class)
public object SomethingElse_Module {
  @Provides
  @IntoMap
  @LazyClassKey(SomethingElse::class)
  public fun provideType(): String =
      "SomethingElse"
}

Note that I had to rename/hide some sensitive details here. Hopefully it still makes sense.

I can work on a reproducer, if required. Didn't dig down into it just yet and wanted to open the issue in the meantime.

Just noting here that Anvil is probably missing generation of the new class for LazyClassKey:

This looks like an Anvil issue.

Anvil uses its own Kotlin plugin to generate factory classes for modules -- i.e. it attempts to replace Dagger's annotation processor and handle code generation itself. In Dagger 2.53 there's an additional generated class for LazyClassKey in modules, so I suspect the issue is that Anvil doesn't yet generate this class.
