至此gradle 升级成功，但由于升级后执行gradle build 发生错误，无法使用新版gradle 编译和打包于是进行降级，降级过程如下：

1、根据brew info gradle 命令 gradle 安装目录为/usr/local/Cellar/gradle

bogon:~ lxrent001$ cd /usr/local/Cellar/gradle

bogon:gradle lxrent001$ ls

3.2.1 4.1

查看到 4.1 的安装目录

2、执行删除 rm -rf 4.1

3、执行 brew switch gradle 3.2.1

bogon:gradle lxrent001$ brew switch gradle 3.2.1

Cleaning /usr/local/Cellar/gradle/3.2.1

2 links created for /usr/local/Cellar/gradle/3.2.1

4、确认是否降级成功

bogon:gradle lxrent001$ gradle -v

------------------------------------------------------------

Gradle 3.2.1

------------------------------------------------------------
