Maven - Environment configuration

Maven is a Java-based tool, so the first thing to do is install the JDK.

System requirements

Project	Requirements
Jdk	Maven 3.3 requires JDK 1.7 or more Maven 3.2 requires JDK 1.6 or more Maven 3.0/3.1 requires JDK 1.5 or more
Memory	There are no minimum requirements
Disk	Maven's own installation requires approximately 10 MB of space. I n addition, the extra disk space will be used for your local Maven repository. The size of your local warehouse depends on usage, but is expected to be at least 500 MB
Operating system	There are no minimum requirements

Step 1: Check the Java installation

Now open the console and execute the java

Operating system	Task	Command
Windows	Open the command console	`c:\> java -version`
Linux	Open the command terminal	`$ java -version`
Mac	Open the terminal	`machine:~ joseph$ java -version`

Let's verify the output on all platforms:

Operating system	Output
Windows	java version "1.6.0_21" Java(TM) SE Runtime Environment (build 1.6.0_21-b07) Java HotSpot(TM) Client VM (build 17.0-b17, mixed mode, sharing)
Linux	java version "1.6.0_21" Java(TM) SE Runtime Environment (build 1.6.0_21-b07) Java HotSpot(TM) Client VM (build 17.0-b17, mixed mode, sharing)
Mac	java version "1.6.0_21" Java(TM) SE Runtime Environment (build 1.6.0_21-b07) Java HotSpot(TM)64-Bit Server VM (build 17.0-b17, mixed mode, sharing)

If you don't have Java installed, install the Java Software Development Kit (SDK) from the following url: http://www.oracle.com/technetwork/java/javase/downloads/index.html. Let's assume that you have installed a version of Java that is 1.6.0-21.

Step 2: Set up the Java environment

Set JAVA_HOME variables and point to the Java installation directory on your machine. For example:

Operating system	Output
Windows	Set the environment variable JAVA_HOME to C:\Program Files\Java\jdk1.6.0_21
Linux	`export JAVA_HOME=/usr/local/java-current`
Mac	`export JAVA_HOME=/Library/Java/Home`

Add the Java compiler address to the system path.

Operating system	Output
Windows	put the string"; C:\Program Files/Java jdk1.6.0_21 ""
Linux	export PATH=$PATH:$JAVA_HOME/bin/
Mac	not required

Use the java-version command mentioned above to verify the Java installation.

Step 3: Download the Maven file

Download Maven 3.2.5: http://maven.apache.org/download.html

Step 4: Unzim the Maven file

Unzim the file to the location you want to install Maven 3.2.5 and you will get the apache-maven-3.2.5 subdirectory.

Operating system	Location (depending on your installation location)
Windows	`C:\Program Files\Apache Software Foundation\apache-maven-3.2.5`
Linux	`/usr/local/apache-maven`
Mac	`/usr/local/apache-maven`

Step 5: Set the Maven environment variable

Add M2_HOME, M2, MAVEN_OPTS to the environment variable.

Operating system	Output
Windows	Use system properties to set environment variables. M2_HOME=C:\Program Files\Apache Software Foundation\apache-maven-3.2.5 M2=%M2_HOME%\bin MAVEN_OPTS=-Xms256m -Xmx512m
Linux	Open the command terminal to set the environment variable. export M2_HOME=/usr/local/apache-maven/apache-maven-3.2.5 export M2=$M2_HOME/bin export MAVEN_OPTS=-Xms256m -Xmx512m
Mac	Open the command terminal to set the environment variable. export M2_HOME=/usr/local/apache-maven/apache-maven-3.2.5 export M2=$M2_HOME/bin export MAVEN_OPTS=-Xms256m -Xmx512m

Step 6: Add the Maven bin directory to the system path

Now add the M2 variable to the system "Path" variable

Operating system	Output
Windows	Add the string "; %M2%" to the end of the system "Path" variable
Linux	export PATH=$M2:$PATH
Mac	export PATH=$M2:$PATH

Step 7: Verify the Maven installation

Now open the console and execute the following mvn command.

Operating system	Output	Command
Windows	Open the command console	`c:\> mvn --version`
Linux	Open the command terminal	`$ mvn --version`
Mac	Open the terminal	`machine:~ joseph$ mvn --version`

Finally, verifying the output of the above command should look like this:

Operating system	Output
Windows	Apache Maven 3.2.5 (r801777; 2009-08-07 00:46:01+0530) Java version: 1.6.0_21 Java home: C:\Program Files\Java\jdk1.6.0_21\jre
Linux	Apache Maven 3.2.5 (r801777; 2009-08-07 00:46:01+0530) Java version: 1.6.0_21 Java home: C:\Program Files\Java\jdk1.6.0_21\jre
Mac	Apache Maven 3.2.5 (r801777; 2009-08-07 00:46:01+0530) Java version: 1.6.0_21 Java home: C:\Program Files\Java\jdk1.6.0_21\jre

Congratulations! Now that you've done all the setup, get started with Apache Maven.
