1.Maven下载

进入官网，进行下载

Maven下载

点击下载，下载好后，找一个你想放的地方解压就行了。
然后解压后的目录是这样子的。

2.Maven配置

2.1maven环境变量配置

打开环境变量,点击新建

• 变量名:MAVEN_HOME
• 变量值:maven下载位置

然后在系统变量中找到Path

添加%MAVEN_HOME%\bin;

打开cmd窗口测试一下看配置是否成功，输入mvn -v

显示版本号,就代表配置成功

2.2maven配置文件

找到你解压的目录，进去找到conf，然后找到settings.xml文件。

1. 本地仓库位置修改

在<localRepository>标签内添加自己的本地仓库位置路径，这个本地仓库位置是自己创建的。

<!-- localRepository
   | The path to the local repository maven will use to store artifacts.
   |
   | Default: ${user.home}/.m2/repository
  <localRepository>/path/to/local/repo</localRepository>
  -->
  <localRepository>D:\OfficeWork\maven\maven-respository</localRepository>

2. 修改maven默认的JDK版本

在<profiles>标签下添加一个<profile>标签，修改maven默认的JDK版本。

<profile>     
    <id>JDK-1.8</id>       
    <activation>       
        <activeByDefault>true</activeByDefault>       
        <jdk>1.8</jdk>       
    </activation>       
    <properties>       
        <maven.compiler.source>1.8</maven.compiler.source>       
        <maven.compiler.target>1.8</maven.compiler.target>       
        <maven.compiler.compilerVersion>1.8</maven.compiler.compilerVersion>       
    </properties>       
</profile>

3. 添加国内镜像源

添加<mirrors>标签下<mirror>，添加国内镜，这样下载jar包速度很快。

3.IDEA配置maven

idea和eclipse都会自带一个maven，但是我们一般都不用，会自己配置一个。

进入全局设置

至此，maven就配置完成了
