### 一、准备工作 ###

##### 1. 下载Maven #####

访问`https://archive.apache.org/dist/maven/maven-3/3.6.0/binaries/` 这个网址，点击`apache-maven-3.6.0-bin.zip`压缩包进行下载。

##### 3. 配置Maven #####

*  在conf下的settings配置文件中进行修改坐标位置与下载镜像源。
 *  1.配置下载坐标的位置：

<localRepository>D:/Tools/repository</localRepository>

*  2.配置下载坐标的镜像源为阿里云镜像：

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

--------------------

### 二、环境搭建 ###
