就是gradle服务器被屏蔽了，需要自己走出去，活在一个自由民主的地方，无奈。
或者就是使用离线版本

2.解决

方法1: 用梯子翻出去后在as的设置里进行如下设定，进行代理设置。之后重启as

方法2:使用gradle的离线包

在下面的位置找到存放离线包的位置，在这个链接里下载gradle的各个版本：Click me！，下载好了放进去  重启as，应该就搞定了
 各操作系统的gradle下载位置

    > windows：C:\用户文件夹\.gradle\wrapper\dists\

 

    > linux：~/.gradle/wrapper/dists/

 

    > mac：~/.gradle/wrapper/dists/
