XxxModule_ProvideXxxFactory classes are not generated in Kotlin

[kubode]

Demonstration codes: https://github.com/kubode/KotlinDaggerIssue

Kotlin does not generate XxxModule_ProvideXxxFactory classes when using same type of @Provides annotated functions.

Modules:

@Module class ApplicationModule {
    @Provides @ApplicationScope fun provideString() = "Application"
}

@Module class ActivityModule {
    @Provides @ActivityScope fun provideString() = "Activity"
}

ActivityModule_ProvideStringFactory and ApplicationModule_ProvideStringFactory are created in java.
(:java:build task is succeeded.)

But, ActivityModule_ProvideStringFactory and ApplicationModule_ProvideStringFactory are not created in Kotlin.
(Code generating task is succeeded.)

$ ./gradlew clean :kotlin:build
...
:kotlin:generateDebugSources
:kotlin:compileDebugKotlin
:kotlin:compileDebugJavaWithJavac

Seems like a kapt bug, not a Dagger bug.

Ok, I'll post to kotlin issue tracker.
Thanks.

@kubode can you link to the kapt issue you created?

[pardom-zz]

@kubode Never mind. I found a workaround here: https://youtrack.jetbrains.com/issue/KT-11201
