msg:Cannot find the getter for attribute 'android:text' with value type java.lang.String in data binding?

I am trying to use data binding in the edittext, In the morning it is working fine but suddenly got the error:

****/ data binding error ****msg:Cannot find the getter for attribute 'android:text' with value type java.lang.String on android.widget.EditText. file:/home/itstym/ApkProjects/Reminder/app/src/main/res/layout/activity_main.xml loc:20:4 - 34:40 ****\ data binding error ****

EditText at line 20:4 -34:40

 <EditText
        app:error="@{login.errorEmail}"
        android:text="@={login.userEmailAddress}"
        android:hint="Email Address"
        android:id="@+id/email_address"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_marginEnd="8dp"
        android:layout_marginStart="8dp"
        android:ems="10"
        android:inputType="textPersonName"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent"
        android:layout_marginTop="24dp"/>

View Holder:

 @Bindable
var userEmailAddress:String = String()
    set(userEmailAddress){
        field=userEmailAddress
        notifyPropertyChanged(R.id.email_address)
        /*to check Email for validation on every character inserted by user*/
        notifyPropertyChanged(BR.errorEmail)
    }
    get() {
    return field
}

What went suddenly wrong?

Solution tried: 1. Invalidate cache and restart. 2. Clean project and Rebuild project.
