How can I resolve this issue?
I installed a new Android Studio on my macOS and I would Like import dataBinding e to follow a tutorial about this technology. But when I import the dependencies and build the following error is shown.

(Android Studio 3.2.1 Build #AI-181.5540.7.32.5056338, built on October 8, 2018 JRE: 1.8.0_152-release-1136-b06 x86_64 JVM: OpenJDK 64-Bit Server VM by JetBrains s.r.o macOS 10.14.1)

I have created a new project and Empty Activity with the following app.gradle and the error persists. It is necessary to uninstall the Android Studio?

apply plugin: 'com.android.application'

apply plugin: 'kotlin-android'

apply plugin: 'kotlin-android-extensions'

apply plugin: 'kotlin-kapt'



android {

    compileSdkVersion 28

    defaultConfig {

        applicationId "br.com.rrlabs.apps.databindingtest"

        minSdkVersion 25

        targetSdkVersion 28

        versionCode 1

        versionName "1.0"

        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"

    }

    buildTypes {

        release {

            minifyEnabled false

            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'

        }

    }

    dataBinding {

        enabled = true

    }

}



dependencies {

    implementation fileTree(dir: 'libs', include: ['*.jar'])

    implementation"org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"

    implementation 'com.android.support:appcompat-v7:28.0.0'

    implementation 'com.android.support.constraint:constraint-layout:1.1.3'

    testImplementation 'junit:junit:4.12'

    androidTestImplementation 'com.android.support.test:runner:1.0.2'

    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'



    //databinding

    kapt "com.android.databinding:compiler:3.1.4"

}

This is working for me: in gradle.properties I add android.databinding.enableV2=true
and also, in app.gradle I insert

databinding {

enabled = true

} 

and comment kapt of app.gradle

//databinding

//kapt "com.android.databinding:compiler:3.1.4"

Tks @Sputnik and @Grendel for the ideas.
Look the git of this project: https://github.com/rodrigoror/MVVMPosts

You forgot equal sign between enabled and true. It should be

databinding {

enabled = true

}
