在Android Studio 3.2 Canary 16 Kotlin项目中找不到符号数据绑定组件

我刚刚在Android Studio 3.2 Canary 16上创建了一个启用Kotlin的新项目。然后，我还启用了数据绑定，但是我得到一个错误，说它找不到DataBindingComponent类

这是我的项目gradle：

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    ext.kotlin_version = '1.2.41'
    ext.android_plugin_version = '3.2.0-alpha10'
    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.2.0-alpha16'
        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
}

buildscript {
    dependencies {
        classpath 'com.android.tools.build.jetifier:jetifier-processor:1.0.0-beta02'
    }
}

我的模块渐变文件：

apply plugin: 'com.android.application'

apply plugin: 'kotlin-android'

apply plugin: 'kotlin-android-extensions'

        }
    }
    dataBinding {
        enabled = true
    }
}

    implementation 'com.android.support:design:27.1.1'
    kapt "com.android.databinding:compiler:3.1.2"
}

我的活动的xml：

<?xml version="1.0" encoding="utf-8"?>
<layout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"

        <variable

            type="net.julianonunes.myapp.RegisterData" />
    </data>

    ....
