Windows 下因为 Eclipse 自带了 Maven 插件，还算够用就懒得安装 Maven 了。在不使用代理的情况下，用 Maven 的下载库不是一般的慢。Eclipse Maven 的插件怎么配置国内的镜像库呢？其实很简单。

创建 settings.xml 文件

注意两个地方： 1、<localRepository>C:\Users\Lenovo\.m2\repository</localRepository> 本地仓库位置 2、镜像配置，选取的是 aliyun 的

<mirrors>
  <mirror>
    <id>alimaven</id>
    <name>aliyun maven</name>
    <url>http://maven.aliyun.com/nexus/content/groups/public/</url>
    <mirrorOf>central</mirrorOf>
  </mirror>
</mirrors>

完整的 settings.xml 文件

<?xml version="1.0" encoding="UTF-8"?>

<!--
 | This is the configuration file for Maven. It can be specified at two levels:
 |
 |  1. User Level. This settings.xml file provides configuration for a single user,
 |                 and is normally provided in ${user.home}/.m2/settings.xml.
 |
 |                 NOTE: This location can be overridden with the CLI option:
 |
 |                 -s /path/to/user/settings.xml
 |
 |  2. Global Level. This settings.xml file provides configuration for all Maven
 |                 users on a machine (assuming they're all using the same Maven
 |                 installation). It's normally provided in
 |                 ${maven.home}/conf/settings.xml.
 |
 |                 NOTE: This location can be overridden with the CLI option:
 |
 |                 -gs /path/to/global/settings.xml
