buildscript {
    ext.kotlin_version = '1.3.11'
    ...
    dependencies {
        ...
        //对kotlin支持
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
        ...
    }
}

2. moudle的build.gradle中依赖

apply plugin: 'kotlin-android'
apply plugin: 'kotlin-kapt'
apply plugin: 'kotlin-android-extensions'
...
dependencies {
//annotationProcessor->kapt
}
