配置maven1.下载地址Download Apache Maven – Maven2.下载maven压缩包并解压3.配置系统环境变量①右键此电脑 → 属性 → 高级系统设置 →环境变量②在系统变量不是用户变量点【新建】变量名MAVEN_HOME大写不能写错变量值maven 解压根目录例 D:\DevEnv\apache-maven-3.9.16③在系统变量找到Path编辑新建一条%MAVEN_HOME%\bin4.cmd mvn -v验证是否成功5.修改 settings.xml最重要本地仓库 阿里云镜像解决下载慢文件位置maven解压目录/conf/settings.xml用记事本 / VSCode 打开ps提前手动新建文件夹D:\DevEnv\apache-maven-3.9.16\Repository①设置本地仓库不占用 C 盘先在 D 盘新建文件夹例如D:\maven_repo用来存放下载的 jar 包。找到settings标签加入下面一行注意不要放到注释乱码localRepositoryD:\DevEnv\apache-maven-3.9.16\Repository/localRepository②添加阿里云镜像国内下载依赖飞快找到文件里的mirrors/mirrors标签把下面 mirror 复制粘贴进去aliyunmaven 阿里云公共仓库 https://maven.aliyun.com/repository/public central 6.完整版?xml version1.0 encodingUTF-8?!-- Licensed to the Apache Software Foundation (ASF) under one or more contributor license agreements.

Global Level. This settings.xml file provides configuration for all Maven | users on a machine (assuming theyre all using the same Maven | installation).
