Maven安装以及常用命令

mvn安装

1.下载地址http://maven.apache.org/download.cgi 下载apache-maven-3.6.3-bin.zip

2.解压到D:\apache-maven-3.6.3

3.将bin目录D:\apache-maven-3.6.3\bin添加到环境变量path

4.测试是否安装成功

C:\Users\admin>mvn --version
Apache Maven 3.6.3 (cecedd343002696d0abb50b32b541b8a6ba2883f)
Maven home: D:\apache-maven-3.6.3\bin\..

　　2.修改国内镜像地址，红色部分为阿里云镜像(将默认国外镜像地址注释)

<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.
     |
    <mirror>
      <id>mirrorId</id>
      <mirrorOf>repositoryId</mirrorOf>
      <name>Human Readable Name for this Mirror.</name>
      <url>http://my.repository.com/repo/path</url>
    </mirror>
     -->
    <mirror>
      <id>aliyunmaven</id>
      <name>aliyunmaven</name>
      <url>https://maven.aliyun.com/repository/public</url>
      <mirrorOf>central</mirrorOf>
    </mirror>
  </mirrors>
