Unix-based Operating Systems (Linux, Solaris and Mac OS X)

    Extract the distribution archive, i.e. apache-maven-3.0.4-bin.tar.gz to the directory you wish to install Maven 3.0.4. These instructions assume you chose /usr/local/apache-maven. The subdirectory apache-maven-3.0.4 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-3.0.4.
    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.
