数据绑定生成错误，android-sunflower示例

Question

I want to try Android JetPack (Navigation Component Framework).I downloaded Android Studio 3.3 Canary 2 for this and copied the application from github( https://github.com/googlesamples/android-sunflower ). But I get an error during build.

Project Gradle =

buildscript {
// Define versions in a single place
ext {
    compileSdkVersion = 28
    minSdkVersion = 19
    targetSdkVersion = 28

    // App dependencies
    constraintLayoutVersion = '1.1.2'
    espressoVersion = '3.0.1'
    glideVersion = '4.4.0'
    gradleVersion = '3.3.0-alpha02'
    gsonVersion = '2.8.2'
    junitVersion = '4.12'
    lifecycleVersion = '1.1.1'
    navigationVersion = '1.0.0-alpha02'
    kotlinVersion = '1.2.50'
    ktlintVersion = '0.24.0'
    ktxVersion = '0.3'
    roomVersion = '1.1.1'
    runnerVersion = '1.0.1'
    supportLibraryVersion = '28.0.0-alpha3'
    workVersion = '1.0.0-alpha04'
}

repositories {
    google()
    jcenter()
}

dependencies {
    classpath "com.android.tools.build:gradle:$gradleVersion"
    classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlinVersion"

You can try Android JetPack (Navigation Component Framework) on Android 3.2 Canary 14 or higher. As tell us here https://developer.android.com/topic/libraries/architecture/navigation/navigation-implementing?utm_source=android-studio&utm_medium=studio-assistant

you can try with Android Studio 3.2 Beta 2.

Althought I am not reproducing the issue by just downloading the project and running it on 3.3 Canary 2.

do you change something apart of the gradle version that is needed?

Greetings.
