Kotlin Dagger 2 androidx fragment不兼容类型

I'm using Dagger 2.21 和 when I try to do

@Module
internal abstract class FragmentModule {
    @ContributesAndroidInjector
    internal abstract fun loginFragment() : LoginFragment
}

和

@Singleton
@Component(modules = [AndroidSupportInjectionModule::class, AppModule::class, ActivityModule::class, ViewModelBuilder::class, ViewModelModule::class, RepositoriesModule::class, ApiModule::class, FragmentModule::class])
interface AppComponent : AndroidInjector<PhotocoApplication> {
    @Component.Builder
    abstract class Builder : AndroidInjector.Builder<PhotocoApplication>()
}

I get this error:

/app/build/generated/source/kapt/debug/com/photoco/app/injection/module/FragmentModule_LoginFragment$app_debug.java:18: error: incompatible types: Class LoginFragment cannot be converted to Class extends Fragment

I have been searching 和 saw that using 2.21 和 setting this gets it to work but no luck yet

和roid.useAndroidX=true ; 和roid.enableJetifier=true

LoginFragment扩展:

dagger.和roid.support.DaggerFragment()

With all this setup can't get it to build, am I missing something here? I can make it work with Activities using DaggerActivity but not with Fragments.

PhotocoApplication extends dagger.和roid.support.DaggerApplication

谢谢
