How To Install Maven On Mac OSX
Since Lion 10.7.1 10.6.8 MacOSx Snow Leopard (correct me if wrong), Mac OS X comes with Apache Maven 3 built in, and can be located at /usr/share/maven。
(标注：安装Eclipse会自带)
1. Maven Built-In
To verify the Maven installation, 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"
1.1 – Where is Maven installed?
A quick check with whereis command :
$ 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. No configuration is needed.
2. Install Maven Manually
After the upgrade of Mac OS X Mavericks, Maven was removed (no idea why). So, You have to install it manually.
2.1 – Download Maven
Download the Maven, for example apache-maven-3.1.1-bin.tar.gz. Extracts it,
tar -xvf apache-maven-3.1.1-bin.tar.gz $pwd /Users/mkyong/apache-maven-3.1.1
2.2 – Set Maven command in environment variable.
Update ~/. bash_profile – create this file if doesn’t exist.
$ vim ~/.bash_profile
export M2_HOME=/Users/mkyong/apache-maven-3.1.1
export PATH=$PATH:$M2_HOME/bin
(标注：按Esc键切换编辑状态与命令状态。在命令状态下，输入:wq回车，代表保存后退出，输入:q!回车，代表不保存就退出)
Restart the terminal. Test it.
$mvn -version Apache Maven 3.1.1 (0728685237757ffbf44136acec0402957f723d9a; 2013-09-17 23:22:22+0800) Maven home: /Users/mkyong/apache-maven-3.1.1 Java version: 1.7.0_05, vendor: Oracle Corporation Java home: /Library/Java/JavaVirtualMachines/1.7.0.jdk/Contents/Home/jre Default locale: en_US, platform encoding: UTF-8 OS name: "mac os x", version: "10.9", arch: "x86_64", family: "mac"
3. Post Configuration
A common post-installation for Maven, change the local repository to another location.
$sudo vim /usr/share/maven/conf/settings.xml $vim /usr/mkyong/maven/conf/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/.
