Maven2 Step by Step
1. Download Maven2 [apache-maven-3.0.2-src.zip] from http://maven.apache.org/download.html
2. Unzip the distribution archive, i.e. apache-maven-3.0.2-bin.zip to the directory you wish to install Maven 3.0.2. These instructions assume you chose C:\Program Files\Apache Software Foundation. The subdirectory apache-maven-3.0.2 will be created from the archive.
Note: It is binary distribution file no need to install. If you want to down load installable file then need to install maven.
3. Configure Maven
a. Windows 2000/XP
Click on Start => My Computer
Right click on My Computer => Properties.
System Properties dialog will be open
Click on Advance => Environment Variables.
Environment Variables dialog will be open
Click on system variable New button and add JAVA_HOME variable with value of java JDK location [C:\Program Files\Java\jdk1.6.0_17] and OK.
Click on system variable New button and add M2_HOME variable with value of maven installation location [C:\Program Files\Apache Software Foundation\apache-maven-3.0.2] and OK.
Note: For Maven < 2.0.9, also be sure that the M2_HOME doesn't have a '\' as last character.
Click on system variable New button and add M2 variable with value of maven bin location [%M2_HOME%\bin] and OK.
Select Path system variable and click on Edit button and add java bin & maven bin location at the end of the path value[%M2%;%JAVA_HOME%\bin] and OK.
Optional: In the same dialog, add the MAVEN_OPTS environment variable in the user variables to specify JVM properties, e.g. the value -Xms256m -Xmx512m. This environment variable can be used to supply extra options to Maven.
Note: It is recommended not to define. Maven internally use system java define values.
Maven configuration completed now test the maven is working or not. Open command prompt and run mvn –version to maven installation test.
b. Unix or Linux
Extract the distribution archive, i.e. apache-maven-3.0.2-bin.tar.gz to the directory you wish to install Maven 3.0.2. These instructions assume you chose /usr/local/apache-maven. The subdirectory apache-maven-3.0.2 will be created from the archive.
In a command terminal, add the M2_HOME environment variable,
E.g. export M2_HOME=/usr/local/apache-maven/apache-maven-3.0.2.
Add the M2 environment variable, e.g. export M2=$M2_HOME/bin.
Optional: Add the MAVEN_OPTS environment variable to specify JVM properties, e.g. export MAVEN_OPTS="-Xms256m -Xmx512m". This environment variable can be used to supply extra options to Maven.
Add M2 environment variable to your path, e.g. export PATH=$M2:$PATH.
Make sure that JAVA_HOME is set to the location of your JDK,
E.g. export JAVA_HOME=/usr/java/jdk1.5.0_02 and that $JAVA_HOME/bin is in your PATH environment variable.
Run mvn --version to verify that it is correctly installed.
