1. 解壓下載的二進位制包
2. 編輯配置檔案 vim ~/.bashrc

新增如下配置

export M2_HOME=/Users/xxxx/development/apache-maven-3.5.4 #maven 二級制包解壓之後存放的位置
export PATH=$PATH:$M2_HOME/bin

4. 及時生效 source ~/.bashrc

5. 驗證 mvn -v 輸出如下提示，說明成功

Apache Maven 3.5.4 (1edded0938998edf8bf061f1ceb3cfdeccf443fe; 2018-06-18T02:33:14+08:00)

7. 修改setting.xml 為了提高第三方庫的下載速度，我需要修改setting.xml。修改預設的遠端倉庫的地址，換成阿里雲提供的遠端倉庫地址，具體操作如下所示：

在maven的解壓目錄中，即/Users/xxxx/development/apache-maven-3.5.4中找到conf/settings.xml檔案，在<mirrors>中新增如下內容。

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

整個<mirrors>節點如下 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>
     -->
 

     <!-- 這是新增加的內容-->
     <mirror>
        <id>nexus-aliyun</id>
        <mirrorOf>*</mirrorOf>
        <name>Nexus aliyun</name>
        <url>http://maven.aliyun.com/nexus/content/groups/public</url>
    </mirror> 
    
  </mirrors>
