This Article provides a complete guide to setup Apache Maven in your Windows or Unix based environment(Linux, Solaris and Mac OS X). Maven version used in this article is Apache Maven 3.1.1.

---

1. Download Apache Maven & Extract it

Download the latest Maven version from Apache Maven site for your environment. Unzip or Untar it on your preferred location in your machine.

On Unix based system (Linux, Solaris and Mac OS X), users can use tar command to do the same

$>tar zxvf apache-maven-3.1.1.tar.gz 

On Windows, users can use tools like 7zip/winzip to unzip apache-maven-3.1.1-bin.zip.

A directory named apache-maven-3.1.1 will be created as result.

2. Set M2_HOME & PATH

Create an environment variable named M2_HOME which refers to directory where maven was untarred/ unzipped. and then add this variable to PATH environment variable.

On Unix based system (Linux, Solaris and Mac OS X)

Add an environment variable named M2_HOME

$>export M2_HOME=/usr/local/apache-maven/apache-maven-3.1.1

Then add this M2_HOME variable to PATH

$>export PATH=$M2_HOME/bin:$PATH.

On Windows

Right click Computer->Properties->Advanced System Settings->’Advanced’ tab-> ‘Environment Variables’

then Add a new ‘User Variable’ named M2_HOME in user variables section

Click OK, then Edit the ‘Path’ user variable to add M2_HOME\bin folder in it.

Click OK.

3. Verify JDK installation & JAVA_HOME

Make sure that JAVA_HOME environment variable is set to the location of your JDK installation, and $JAVA_HOME/bin is in your PATH environment variable.

On Unix based system (Linux, Solaris and Mac OS X)

$>export JAVA_HOME=/usr/java/jdk1.6.0_45
$>export PATH=$JAVA_HOME/bin:$PATH.

On Windows

It’s done.

4. Verify Maven setup

Execute command mvn --version to verify maven installation (same command for both windows and Unix).

E:\>mvn --version
