maven安装

1, 下载 maven

到官网下载: http://maven.apache.org/download.cgi

2, 配置仓库

<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

   |

  <localRepository>/path/to/local/repo</localRepository>
  -->
  <localRepository>C:maven
epository</localRepository>

3, 配置镜像

<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>alimaven</id>
        <mirrorOf>central</mirrorOf>
        <name>aliyun maven</name>
        <url>http://maven.aliyun.com/nexus/content/repositories/central/</url>
    </mirror>
  </mirrors>

4, 配置环境变量

　　找到 maven bin 目录, 我的是: C:mavenapache-maven-3.5.4in

　　编辑 Path 系统变量, 添加 bin 目录即可(如果是 Win7 注意分号, win10 直接点击新建)

5, 测试

　　输入 mvn -version

C:Usershuanggy>mvn -version
