How to use AndroidAnnotation @SharedPref with Kotlin

I'm trying to use AndroidAnnotations @SharefPref within kotlin, but Iget following error

org.androidannotations.annotations.sharedpreferences.Pref can only be used on an element that extends org.androidannotations.api.sharedpreferences.SharedPreferencesHelper

What am I doing wrong?

//Interface
@SharedPref(SharedPref.Scope.APPLICATION_DEFAULT)
open interface MyPreferences {
    @DefaultInt(-1)
    fun someIntValue():Int
}

//Fragment
@Pref
lateinit open var sharedPref:CongressPreferences_

//usage within fragment
val get: Int = sharedPref.selectedEventId().get()

I just wanna extend on @WonderCsabo 's answer. His answer almost saved me, but not fully.

After adding this to my app label build gradle.

kapt { correctErrorTypes = true }

I wasn't able to run my app.

Then I closed my android studio and then run Android studio again as administrator. Voila! it works like charm.

Thank you @WonderCsabo
