最近引入了一个maven项目，好多依赖包都cannot resolve，查了下，应该是墙的原因，后来通过把maven的仓库地址换成了阿里云的就解决了。

在 ~/.m2/ 下新建一个settings.xml,然后复制如下代码,就ok了

<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0
                     http://maven.apache.org/xsd/settings-1.0.0.xsd">
