Gradle的使用

最近研究Android Studio打多渠道包，现总结如下:

一.Gradle最新版本2.4,下载地址: https://gradle.org/downloads/

二.Gradle官方文档教程 http://tools.android.com/tech-docs/new-build-system/user-guide

三.Gradle的安装,

   1.解压下载的安装包;

   2.配置变量环境 GRADLE_HOME

   3.添加bin目录到path环境变量下;

   4.运行gradle -v 验证是否安装好;

运行gradle clean  

运行gradel build　即打包

或gradel assemble[release|debug|channel]buildle
