mvn 换源

maven的默认镜像，有的时候，下载jar包的非常的慢。换了阿里镜像速度快了很多。

1，查找maven的配置文件

MacBook-Pro:conf zhangying$ mvn -version
Apache Maven 3.5.0 (ff8f5e7444045639af65f6095c62210b5713f426; 2017-04-04T03:39:06+08:00)
Maven home: /usr/local/Cellar/maven/3.5.0/libexec  //maven home路径
Java version: 1.8.0_112, vendor: Oracle Corporation
Java home: /Library/Java/JavaVirtualMachines/jdk1.8.0_112.jdk/Contents/Home/jre
Default locale: zh_CN, platform encoding: UTF-8
OS name: "mac os x", version: "10.12.6", arch: "x86_64", family: "mac"

mac，centos都可以通过查看版本的方式来查找路径，其他linux应当一样。

2，配置settings.xml

$ cd /usr/local/Cellar/maven/3.5.0/libexec/conf
$ cp settings.xml settings.xml_bak
$ vim setting.xml //将mirrors改成如下内容
