2) 下载Maven

http://maven.apache.org/

http://maven.apache.org/download.cgi

Maven 3.3.3 (Binary tar.gz)

Maven 3.3.3 (Binary zip)

Maven 3.3.3 (Source tar.gz)

Maven 3.3.3 (Source zip)

注：具体版本以官网为准。

这几个包的区别：

Installing Maven
  ----------------
1) Unpack the archive where you would like to store the binaries, eg:

Unix-based operating systems (Linux, Solaris and Mac OS X)
 tar zxvf apache-maven-3.x.y.tar.gz

Windows
 unzip apache-maven-3.x.y.zip

2) A directory called "apache-maven-3.x.y" will be created.
3) Add the bin directory to your PATH, eg:

Unix-based operating systems (Linux, Solaris and Mac OS X)
 export PATH=/usr/local/apache-maven-3.x.y/bin:$PATH

Windows
 set PATH="c:\program files\apache-maven-3.x.y\bin";%PATH%

4) Make sure JAVA_HOME is set to the location of your JDK

5) Run "mvn --version" to verify that it is correctly installed.

所以区别显而易见：

.tar.gz用于linux

.zip 用于windows

另外src.zip 是源码

.zip 是安装包

下载之前版本

https://maven.apache.org/download.cgi

If you still want to use an old version you can find more information in the Maven Releases History and can download files from the archives for versions 3.0.4+ and legacy archives for earlier releases.
