Kotlin在Android Studio 3.0 Canary 2中使用Android DataBinding
我的项目有2个模块，它们是app和apphelper作为一个库。 我一直在尝试使用android数据绑定与它kotlin，但我无法弄清楚为什么当我建立项目时，它不断显示我这些错误：
失败：生成失败，出现异常。

我将kotlin版本降级为“1.1.2-2”以避免错误，并在local.properties中添加了“ kotlin.incremental = false ”
这里是我所有的build.gradle文件：

主gradle构建脚本：
// Top-level build file where you can add configuration options common to all sub-projects/modules. buildscript { ext.kotlin_version = '1.1.2-2' ext.android_plugin_version = '3.0.0-alpha2' repositories { jcenter() maven { url 'https://maven.google.com' } maven { url 'https://maven.fabric.io/public' } } dependencies { classpath 'io.fabric.tools:gradle:1.+' classpath "com.android.tools.build:gradle:$android_plugin_version" classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version" // NOTE: Do not place your application dependencies here; they belong // in the individual module build.gradle files } } allprojects { repositories { jcenter() maven { url 'https://maven.google.com' } mavenCentral() } } task clean(type: Delete) { delete rootProject.buildDir }
任何人都有我的问题，请分享解决方案。 谢谢。
去掉：
kapt { generateStubs = true }
并添加到依赖关系：
kapt "com.android.databinding:compiler:$android_plugin_version"
它现在工作，我只是降级com.android.tools.build:gradle为2.3.2 ，更改distributionUrl为https://services.gradle.org/distributions/ gradle-3.3-all .zip并使用稳定的Android Studio（ 2.3.2 ）。 Android Studio 3.0稳定版发布时，应该清除这个问题。
我认为，正确的解决方法是等待Google解决： https ： //issuetracker.google.com/issues/62170415
或现在使用替代方法 ，我在这里描述： https : //stackoverflow.com/a/44346259/4024146
