Maven Installation: Mac OS X

Maven Installation: Mac OS X

Note: All lines in code blocks should be sequentially executed in Terminal.

Install Homebrew.

Homebrew is an OS X package manager that allows convenient installation of thousands of modules.

ruby -e "$(curl -fsSL https://raw.github.com/Homebrew/homebrew/go/install)"

Be patient until Homebrew has completed installation.

Install Maven.

This is where Homebrew's magic comes into play.

Run the following command:

brew install maven

This simple command will download, extract, and install the latest version of Maven and its respective dependencies.

Set environment variables.

Note: This tutorial assumes you installed Apache Maven 3.2.1. Replace 3.2.1 with the version you have downloaded. Check your version like so:

mvn --version

Unfortunately, you must manually export environment variables for Maven to properly function.

export M2_HOME=/usr/local/Cellar/maven/3.2.1
export M2=$M2_HOME/bin
export PATH=$M2:$PATH

These commands will set Maven's environment variables in paths according to Homebrew's installation process.

Locate the path of your JDK installation and run the following command:

Note: The following command assumes your Java JDK installation is located here:

/Library/Java/JavaVirtualMachines/jdk1.7.0_51.jdk/Contents/Home

export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.7.0_51.jdk/Contents/Home
export PATH=$JAVA_HOME/bin:$PATH

Verify Maven is installed correctly.

Simply check the version and make sure no errors pop up.

mvn --version

If all is well, congratulations! You've successfully installed Maven on Mac OS X.
