Android Studio 3 unable to build kotlin fragment

Im trying to use Kotlin with Android Studio 3.0 with my existing project. I have created a fragment using kotlin. Im trying to use the kotlin fragment in my Java Activity. But everytime i try to run it I get 

Error:(209, 5) error: cannot find symbol class BlankFragment

BlankFragment.kt

import android.content.Context
import android.net.Uri
import android.os.Bundle
import android.support.v4.app.Fragment
import android.view.LayoutInflater
import android.view.View
import android.view.ViewGroup

class BlankFragment : Fragment() {

    // TODO: Rename and change types of parameters
    private var mParam1: String? = null
    private var mParam2: String? = null

    private var mListener: OnFragmentInteractionListener? = null

    public override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        if (getArguments() != null) {
            mParam1 = getArguments().getString(ARG_PARAM1)
            mParam2 = getArguments().getString(ARG_PARAM2)
        }
    }

    override fun onCreateView(inflater: LayoutInflater, container: ViewGroup, savedInstanceState: Bundle?): View
            = FragmentUi<Fragment>().createView(AnkoContext.create(ctx, this))

}

class FragmentUi<T>: AnkoComponent<T> {
    override fun createView(ui: AnkoContext<T>) = with(ui) {
        verticalLayout {
            textView {
                text = R.string.app_name

            }

Finally was able to get it working. For anyone who is going through a similar problem.

project build.gradle

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    ext.kotlin_version = '1.1.3'

You seem to be missing all Kotlin dependencies other than having the version declared (you should probably update that to 1.1.3 as well, which is the latest available as of now).

You can configure your project in two ways:

  • Remove the Kotlin version you have declared, and then go to Tools -> Kotlin -> Configure Kotlin in Project, and follow the steps presented there.
  • Alternatively, you can do it in a more manual way by following the steps described here to set up the Kotlin Gradle plugin, including following the link that's there and setting up the standard library dependency as well.
