Kotlin get type of generic class without instance

Question

Hey want go get Type of T , but I can not get it from instance, I have to get it from class parameter, how to do it?

abstract class ViewModelFragment<T : ViewModel>{
    protected lateinit var mViewModel: T

    override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
       mViewModel = ViewModelProviders
                    .of(scope)
                    .get(getGenericTClass())
    // .get(mViewModel.javaClass) // not working either

   }

   inline fun<reified R> getGenericTClass() = R::class.java

}

Right now compiler complains

Cannot use 'T' as refined class type. Use Class instead.

I have the same issue and code below helped me:

  val persistentClass = (javaClass.genericSuperclass as ParameterizedType).actualTypeArguments[0] as Class<T>
    mViewModel = ViewModelProviders.of(this, viewModelsFactory).get(persistentClass)
