Maven配置

一、maven的安装

首先，先到官网去下载maven。这里是官网的地址：http://maven.apache.org/download.cgi 请选择最新的版本下载：

解压

二、路径配置

右键“计算机”，选择“属性”，之后点击“高级系统设置”，点击“环境变量”，来设置环境变量

有以下系统变量需要配置：

新建

变量名   MAVEN_HOME  

变量值：D:\Program Files\apache-maven-3.9.0
1
2
3

编辑系统变量 Path 添加变量值：

%MAVEN_HOME%\bin
1

最后检验配置是否成功：用win键+R，来打开命令行提示符窗口，即Dos界面，输入

mvn -version 
1

若出现以下情况说明配置成功

三、修改Maven依赖下载源

1、首先打开自己的maven安装目录，下面找到conf文件夹，打开settings.xml文件

2、直接复制下面的内容覆盖，切换为阿里源

<?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">

     | The path to the local repository maven will use to store artifacts.
     |
     | Default: ${user.home}/.m2/repository
    <localRepository>/path/to/local/repo</localRepository>
    -->
    <mirrors>
        <!-- mirror
         | Specifies a repository mirror site to use instead of a given repository. The repository that
         | this mirror serves has an ID that matches the mirrorOf element of this mirror. IDs are used
         | for inheritance and direct lookup purposes, and must be unique across the set of mirrors.
         |

         -->

            <url>http://repo.maven.apache.org/maven2</url>

四、修改库文件路径

maven作为非常强大的一个组织和管理工具，但是它的默认仓库放在C盘文档目录下，这样万一重装电脑会将下载的

jar包全部消除，而且永久以后库文件积累太多，容易造成电脑缓慢。对于项目来说重新部署虽然不是难事，但是我们

可以做到将仓库搬到另一个位置，这样就可以一劳永逸了。

使用ctrl+f在settings.xml寻找localrepository字样，出现如下所示，下面将这个标签改为你想要的路径：

例如

 <localRepository>D:/Program Files/apache-maven-repository/repository</localRepository>
1

创建你在settings.xml中指定真实仓库路径，并将修改后的settings.xml文件复制一份放在当前的目录下（原来的不要删除掉）
