一、需要准备的东西

二、官网下载：
http://maven.apache.org/download.cgi
System Requirements
| Java Development Kit (JDK) | Maven 3.3+ require JDK 1.7 or above to execute – they still allows you to build against 1.3 and other JDK versions by Using Toolchains |
| Memory | No minimum requirement |
| Disk | Approximately 10MB is required for the Maven installation itself. In addition to that, additional disk space will be used for your local Maven repository. The size of your local repository will vary depending on usage but expect at least 500MB. |
| Operating System | No minimum requirement. Start up scripts are included as shell scripts and Windows batch files. |
因为 安装包是 java 写的，里面的启动文件 即有 Windows的mvn.cmd 也有linux的mvn 所以没有 按不同的系统发布不同的安装包。
