在工程gradle的依賴里面添加就好。

classpath 'com.github.dcendents:android-maven-gradle-plugin:1.3'
classpath 'com.jfrog.bintray.gradle:gradle-bintray-plugin:1.2'

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.1.2'
        classpath 'com.github.dcendents:android-maven-gradle-plugin:1.3'
        classpath 'com.jfrog.bintray.gradle:gradle-bintray-plugin:1.2'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}
