How-To: Install Maven

Step-by-step instructions for getting Maven up and running to support your development.

Current Maven Version: 2.2.1

Use other versions at your peril.

Note: Mac OS X comes pre-installed with a copy of Maven 2.2.1; be sure to double-check your version from the command line after following the steps below, or things will break.

Step 1: Get the Maven Binary

You can download that here. No other plugins are required. (Version 2.2.1 zip file)

Step 2: Unpack the Binary on Your System

Mac

Explode the zip on your system to /usr/local

Windows

Extract the downloaded Maven zip file to the root of the C: drive, this will create a maven-2.2.1 folder.

Step 3: Set Your Environment Path

Mac

Add a M2_HOME environment variable to your ~/.bash_profile and point it to your download, e.g.:

export M2_HOME=/usr/local/apache-maven-2.2.1

Add the $M2_HOME/bin directory to your path, before /usr/bin.

Windows

Adjust the System Path Variable, appending a semi-colon and the location of the maven\bin directory as shown in this example as C:\maven-2.2.1\bin

Add a M2_HOME environment variable as well. If you want to get fancy, you can define that first and substitute %M2_HOME%\bin in the System Path variable.

Step 4: Test Your Installation

Mac

notch:~ gw$ mvn --version
Maven version: 2.2.1
Java version: 1.5.0_13

Windows

Open a new command window (the changes to the Path variable will not take effect in command windows opened previously) just as you had done to verify the correct operation of the Java Development Kit in the previous step. At the command prompt type:

mvn –version

You should see the response as indicated:

Step 5: Configure your Repository Settings

Create a file called settings.xml in your OS user home directory as follows:

OS	Location
OSX	~/.m2
Windows	%APPDATA%\..\.m2 (running mvn clean will create this for you in your Documents and Settings folder, or read this article for Windows installation tips)

Copy the contents of our settings.xml - For Licensed Customers and Partners  to the file and save it.

Customize the properties to suit your environment. Look for:

<properties>     <!-- Defines Tomcat home directory for Cargo -->     <tomcat.home><![CDATA[/usr/local/apache-tomcat-6.0.14\]\]\></tomcat.home>     <tomcat6.home><![CDATA[/usr/local/apache-tomcat-6.0.14\]\]\></tomcat6.home>     <!-- Specifies whether Cargo should stay alive after running integration tests -->     <cargo.wait>false</cargo.wait>     <!-- Overrides the value for the <setup> tag in jive_startup.xml -->     <jive.setup>true</jive.setup>     <!-- Your SVN credentials>     <svn.username>yourname</svn.username>     <svn.password>yourpass</svn.password> </properties>

Properties defined in the settings.xml file are global and will apply to all Maven projects. Properties that may vary from project to project, such as <jiveHome> should not be defined here.
