android-studio - Android studio 3.1 beta DataBinding 和 kapt

Question

我正在尝试实现一个新功能“您现在可以将 LiveData 对象用作数据绑定(bind)表达式中的可观察字段”，如文档所述 https://androidstudio.googleblog.com/2017/12/android-studio-31-canary-6-is-now.html
下载 AS 3.1 beta 后，我无法编译我的项目
我收到不同的消息，例如“在 org.gradle.api.Project 类型的项目 ':app' 上找不到参数 [com.android.databinding:compiler:2.3.0] 的方法 kapt()”

这是我的gradle文件:

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

buildscript {
ext.kotlin_version = '1.2.30'
ext.google_ver = '27.1.0'
ext.google_play_ver = '11.8.0'
ext.retrofit_ver = '2.3.0'
ext.arch_components_ver = '1.1.1'

repositories {
    jcenter()
    google()
    maven { url "https://kotlin.bintray.com/kotlinx" }

    mavenLocal()
}
dependencies {
    classpath 'com.android.tools.build:gradle:3.2.0-alpha07'

    // NOTE: Do not place your application dependencies here; they belong
    // in the individual module build.gradle files
    classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    classpath "org.jetbrains.kotlin:kotlin-android-extensions:$kotlin_version"
    classpath 'com.google.gms:google-services:3.1.2'
}
}
allprojects {
repositories {
    jcenter()
    mavenCentral()
    maven { url "https://jitpack.io" }
    maven {
        url "https://maven.google.com"
    }
    maven { url "https://kotlin.bintray.com/kotlinx" }
    google()
    flatDir { dirs 'libs' }
}
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

好的，如果您使用的是 'com.android.tools.build:gradle:3.2.0-alpha07' 的话，请删除这些行

androidExtensions {
experimental = true
}
