Installing Apache Maven-Java tool

Download maven.

Windows OS:

  1. Unzip the distribution archive, i.e. apache-maven-3.0.4-bin.zip to the directory you wish to install Maven 3.0.4. These instructions assume you chose C:\Program Files\Apache Software Foundation. The subdirectory apache-maven-3.0.4 will be created from the archive.
  2. Add the M2_HOME environment variable. [almost similar as this]: adding the M2_HOME variable in the user variables with the value C:\Program Files\Apache Software Foundation\apache-maven-3.0.4. Be sure to omit any quotation marks around the path even if it contains spaces.
  3. In the same dialog, add the M2 environment variable in the user variables with the value %M2_HOME%\bin.
  4. In the same dialog, update/create the Path environment variable in the user variables and prepend the value %M2% to add Maven available in the command line.
  5. In the same dialog, make sure that JAVA_HOME exists in your user variables or in the system variables and it is set to the location of your JDK, e.g.C:\Program Files\Java\jdk1.5.0_02 and that %JAVA_HOME%\bin is in your Path environment variable.
  6. Open a new command prompt and run mvn –version to verify that it is correctly installed.

Linux based/Ubuntu Operating Systems:

  1. Extract the distribution archive, to the directory you wish to install Maven 3.0.4. These instructions assume you chose /home/username/java/tools/maven.
  2. Open terminal and type:  gedit ~/.bashrc
  3. Set environment variable by adding the following lines at the bottom of .bashrc :
    •  export M2_HOME=/home/username/java/tools/maven
    • export M2=$M2_HOME/bin
    • export PATH=$M2:$PATH
    • export JAVA_HOME=/usr/lib/jvm/jdk-default #if JAVA_HOME not exist.
  4. Run mvn –version to verify that it is correctly installed.
