Android Kotlin Two-Way databinding BR class error - kotlin

Question

I'am trying to do a basic android application using kotlin and two way data binding to show on a text view the changes in a edit text. But i'am getting this error :
w: [kapt] Incremental annotation processing requested, but support is disabled because the following processors are not incremental: android.databinding.annotationprocessor.ProcessDataBinding (DYNAMIC).
when i'am trying to do with one way data binding it is working well it show me the Contact class's name field successful
my codes:
build.gradle(Project)
// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
ext.kotlin_version = '1.3.61'
repositories {
google()
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.5.3'
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
google()
jcenter()
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}
build.gradle(module:app)
apply plugin: 'com.android.application'

import androidx.databinding.Bindable
class Contact( var Id:Int,
var Name:String,
var Email:String):BaseObservable() {

var _name: String = Name
set(value) {

notifyPropertyChanged(BR._name)
}
get() = field

unfortunately, this error has not yet been resolved. I hope the warning will be resolved in the next update. I've been waiting for updates since November because of this warning
