2.安装

解压

解压到“D:\YDGreen\”

设置环境变量

M2_HOME: D:\YDGreen\apache-maven-3.6.1-bin\apache-maven-3.6.1 Path后面加上：%M2_HOME%\bin

---

3.配置

修改“安装目录\conf\settings.xml”文件。

修改仓库位置

若不修改默认为${user.home}/.m2/repository。

<localRepository>E:/YDSHARE/MavenRepo</localRepository>

使用阿里的云镜像库

<mirrors> <mirror> <id>nexus-aliyun</id> <mirrorOf>*</mirrorOf> <name>Nexus aliyun</name> <url>http://maven.aliyun.com/nexus/content/groups/public</url> </mirror> </mirrors>

最终的settings.xml如下所示

下面已将注释去掉：

<?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"> <localRepository>E:/YDSHARE/MavenRepo</localRepository> <pluginGroups> </pluginGroups> <proxies> </proxies> <servers> </servers> <mirrors> <mirror> <id>nexus-aliyun</id> <mirrorOf>*</mirrorOf> <name>Nexus aliyun</name> <url>http://maven.aliyun.com/nexus/content/groups/public</url> </mirror> </mirrors> <profiles> </profiles> </settings>

4. IDEA配置Maven

File -> Other Settings -> Settings for New Projects… -> Build,Execution,Deployment -> Build Tools -> Maven

Maven home directory设置为“D:\YDGreen\apache-maven-3.6.1-bin\apache-maven-3.6.1”。User settings file设置为“D:\YDGreen\apache-maven-3.6.1-bin\apache-maven-3.6.1\conf\settings.xml”。local repository会自动识别为“E:\YDSHARE\MavenRepo”（我们刚才设置的本地仓库）。File -> Setting下的配置参照上面。
