cannot access DataBindingComponent dagger 2

Question

I want to inject data binding to activity using Dagger 2. I have a problem with its. I don't understand what is wrong.

ERROR

cannot access DataBindingComponent class file for androidx.databinding.DataBindingComponent not found

And my code:

MainActivity.kt

class MainActivity : AppCompatActivity() {
    @Inject lateinit var bindingUtil: ActivityMainBinding

    override fun onCreate(savedInstanceState: Bundle?) {
        val stepperContainer = (applicationContext as StepperApplication).stepperContainer
        stepperContainer.inject(this)
        super.onCreate(savedInstanceState)
    }
}

StepperApplication.kt

class StepperApplication : Application() {
    val stepperContainer by lazy {
        DaggerStepperComponent.builder().context(ContextModule(applicationContext)).build()
    }

    override fun onCreate() {
        super.onCreate()
    }
}

StepperComponent.kt

@Singleton
@Component (modules = [ContextModule::class])
interface StepperComponent {
    fun inject(activity: MainActivity)
}

ContextModule.kt

@Module
class ContextModule (var context: Context) {

    @Singleton
    @Provides
    fun context() : Context {
        return context
    }
}

ActivityMainModule.kt

@Module (subcomponents = [ActivityMainComponent::class])
class ActivityMainModule (var activity: MainActivity) {
    @Provides
    fun activityMainBinding(activity: MainActivity) : ActivityMainBinding {
        return DataBindingUtil.setContentView(activity, R.layout.activity_main)
    }
}

ActivityMainComponent.kt

@Subcomponent
interface ActivityMainComponent {

    @Subcomponent.Builder
    interface Builder {
        fun activityMain(activity: MainActivity) : Builder
        fun build() : ActivityMainComponent
    }
}

Gradle

    <ScrollView
        android:layout_width="match_parent"
        android:layout_height="match_parent">

        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:orientation="vertical" >

            <TextView
                android:id="@+id/textView"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="Hello World!" />
        </LinearLayout>
    </ScrollView>

</androidx.constraintlayout.widget.ConstraintLayout>

What is the problem and how to solve it?
