How to install Maven on Mac
By: Slav Kurochkin
First lets check if you have MVN on your computer by running simple command in terminal: mvn -version, if you are not getting any result probably you don’t have Maven installed, you will need to download it and follow the instructions from official website.
On Mac it would be:
Unix-based Operating Systems (Linux, Solaris and Mac OS X)
1. Extract the distribution archive, i.e. apache-maven-3.2.2-bin.tar.gz to the directory you wish to install Maven 3.2.2. These instructions assume you chose /usr/local/apache-maven. The subdirectory apache-maven-3.2.2 will be created from the archive.
2. In a command terminal, add the M2_HOME environment variable, e.g. export M2_HOME=/usr/local/apache-maven/apache-maven-3.2.2.
3. Add the M2 environment variable, e.g. export M2=$M2_HOME/bin.
4. Optional: Add the MAVEN_OPTS environment variable to specify JVM properties, e.g. export MAVEN_OPTS="-Xms256m -Xmx512m". This environment variable can be used to supply extra options to Maven.
5. Add M2 environment variable to your path, e.g. export PATH=$M2:$PATH.
6. Make sure that JAVA_HOME is set to the location of your JDK, e.g. export JAVA_HOME=/usr/java/jdk1.7.0_51 and that $JAVA_HOME/bin is in your PATH environment variable.
7. Run mvn --version to verify that it is correctly installed.
