eclipse_maven换源

1. 手动新增一个xml文件：

<?xml version="1.0" encoding="UTF-8"?>
<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">
    <mirrors>
        <mirror>
            <id>nexus</id>
            <name>Tedu Maven</name>
            <mirrorOf>*</mirrorOf>
            <url>http://maven.aliyun.com/nexus/content/groups/public</url>
        </mirror>
    </mirrors>
</settings>

2.打开window-->preferences-->maven-->user settings

完成了~
