How To Install Maven On Mac OSX

By mkyong

Since Lion 10.7.1 (correct me if wrong), Mac OS X comes with Apache Maven 3 built in, and can be located at/usr/share/maven.

1. Maven Verification

In terminal, issue the command mvn -version.

$mvn -version
 
Apache Maven 3.0.3 (r1075438; 2011-03-01 01:31:09+0800)
Maven home: /usr/share/maven
Java version: 1.6.0_33, vendor: Apple Inc.
Java home: /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home
Default locale: en_US, platform encoding: MacRoman
OS name: "mac os x", version: "10.7.4", arch: "x86_64", family: "mac"

2. So, where is Maven installed?

A quick check with whereis

$ whereis mvn
/usr/bin/mvn

$ cd /usr/bin
$$ ls -ls | grep mvn
 8 lrwxr-xr-x   1 root   wheel        24 May 23 15:57 mvn -> /usr/share/maven/bin/mvn

By default, Maven is installed at /usr/share/maven.

3. Change Maven local repository

A common post-installation for Maven, change the local repository to another location.

$sudo vim /usr/share/maven/conf/settings.xml

settings.xml

<!-- localRepository
   | The path to the local repository maven will use to store artifacts.
   |
   | Default: ~/.m2/repository
  <localRepository>/path/to/local/repo</localRepository>
  -->
<localRepository>/Users/mkyong//maven/repo/</localRepository>

Above example changed the default repository from ~/.m2/repository to /Users/mkyong//maven/repo/.

Note
For older Mac OS, you need to download, extra, and configure the environment manually. Please refer to this guide.
