报错了~~wing大师，databinding和kotlin不兼容，修改app里面的build文件
在app build.gradle中添加如下代码即可解决
kapt {
generateStubs = true
}

dependencies {
//...
kapt "com.android.databinding:compiler:2.3.0"
}

工程的gradle的classpath设置为：
classpath 'com.android.tools.build:gradle:2.4.0-alpha7'
app的gradle的databinding设置为
kapt 'com.android.databinding:compiler:2.4.0-alpha7'

解决方案：https://stackoverflow.com/questions/39764704/errorexecution-failed-for-task-appcompiledebugkotlinafterjava。将project 和app 的build.gradle中的kotlin的版本改为1.1.2即可解决完成编译运行

测试最新版的3.0可以编译，更新studio再试下~
