How to resolve errors with the configuration of task ':app:kaptDebugKotlin'?

Question

I'm trying to build Android app in Kotlin using dataBinding and when I'm trying to compile this code

@Bindable
var progress:Int=1

@NotNull
@InverseBindingAdapter(attribute = "progress")
 fun  SeekBar.getProgress():Int{
    return this.progress
}

@BindingAdapter(value = ["progressAttrChanged"])
fun setListeners(seekBar: SeekBar,inverseBindingListener: InverseBindingListener){
    var listener=object: SeekBar.OnSeekBarChangeListener{
        override fun onProgressChanged(seekBar: SeekBar?, Progress: Int, fromUser: Boolean) {
            progress=Progress
            mBeatBox.mRange=progress/66.67 as Float
            inverseBindingListener.onChange()
        }

        override fun onStartTrackingTouch(seekBar: SeekBar?) {

        }

        override fun onStopTrackingTouch(seekBar: SeekBar?) {

        }
    }
    seekBar.setOnSeekBarChangeListener(listener)
}

I get this errors https://ibb.co/cBHRwx.

Here is view of modelView

 <data>
    <variable
        name="viewModel"
        type="com.bignerdranch.android.beatboxkotlin.Models.BeatBoxViewModel"/>
</data>
....
 <TextView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        tools:text="progres"
        android:gravity="center"
        android:layout_weight="9"/>
    <android.support.v7.widget.AppCompatSeekBar
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_weight="9"
        app:progress="@={viewModel.progress}"/>

How can I solve this?

I solved this error in this way

Updated viewModel `

var progress:Int=mBeatBox.mRange.toInt()
@Bindable set(value){field=value;notifyChange()}
@Bindable get()=field

fun getEditListener():SeekBar.OnSeekBarChangeListener{
var listener=object: SeekBar.OnSeekBarChangeListener{
        override fun onProgressChanged(seekBar: SeekBar?, Progress: Int, fromUser: Boolean) {
            progress=Progress
            mBeatBox.mRange=(progress/66.67).toFloat()
        }
        override fun onStartTrackingTouch(seekBar: SeekBar?) {
        }
        override fun onStopTrackingTouch(seekBar: SeekBar?) {
        }
    }
    return listener
}`

And View looks like:

 <TextView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        tools:text="progress"
        android:gravity="center"
        android:layout_weight="9"
        android:text="@{String.valueOf(viewModel.progress)}"/>
    <android.support.v7.widget.AppCompatSeekBar
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_weight="9"
        app:OnSeekBarChangeListener="@{viewModel.EditListener}"/>

Not sure exactly what your error is pointing to, but looks like there's already a SeekbarBindingAdapter defined in the library, so you probably don't need to define your own. If you want to update things when progress changes, override set or use ObservableInt with an OnPropertyChangedCallback
