友情提示：Ubuntu 14.04 下，安装 Java8

• 下载Maven

http://www-eu.apache.org/dist/maven/maven-3/

，
打开上述链接，进入相应目录，下载 特定的 Maven 版本。笔者选择的是 apache-maven-3.3.9-bin.tar.gz。

• 配置Maven环境变量

将 apache-maven-3.3.9-bin.tar.gz 解压至指定目录

blockchain@ThinkPad-T460:~$ tar -zxvf ~/Downloads/apache-maven-3.3.9-bin.tar.gz -C ~

编辑 主目录下的 .bashrc 文件

blockchain@ThinkPad-T460:~$ vim ~/.bashrc

在文件末尾添加

export MAVEN_HOME=$HOME/apache-maven-3.3.9
export PATH=$PATH:${MAVEN_HOME}/bin

使配置立即生效

blockchain@ThinkPad-T460:~$ source ~/.bashrc

查看Maven版本

blockchain@ThinkPad-T460:~$ mvn -version

找到mirrors镜像节点，增加mirror节点，如下所示：

  <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>
      <name>aliyun maven</name>
      <url>http://maven.aliyun.com/nexus/content/groups/public/</url>
      <mirrorOf>central</mirrorOf>
    </mirror>
  </mirrors>
