Maven - Environment Setup


Advertisements


Maven is a Java based tool, so the very first requirement is to have JDK installed on your machine.

System Requirement

JDK 1.7 or above.
Memory No minimum requirement.
Disk Space No minimum requirement.
Operating System No minimum requirement.

Step 1 - Verify Java Installation on your Machine

Open console and execute the following java command.

OS Task Command
Windows Open Command Console c:\> java -version
Linux Open Command Terminal $ java -version
Mac Open Terminal machine:~ joseph$ java -version

Let's verify the output for all the operating systems −

OS Output
Windows

java version "1.7.0_60"

Java(TM) SE Runtime Environment (build 1.7.0_60-b19)

Java HotSpot(TM) 64-Bit Server VM (build 24.60-b09, mixed mode)

Linux

java version "1.7.0_60"

Java(TM) SE Runtime Environment (build 1.7.0_60-b19)

Java HotSpot(TM) 64-Bit Server VM (build 24.60-b09, mixed mode)

Mac

java version "1.7.0_60"

Java(TM) SE Runtime Environment (build 1.7.0_60-b19)

Java HotSpot(TM) 64-Bit Server VM (build 24.60-b09, mixed mode)

If you do not have Java installed, install the Java Software Development Kit (SDK) from https://www.oracle.com/technetwork/java/javase/downloads/index.html. We are assuming Java 1.7.0.60 as installed version for this tutorial.

Step 2 - Set JAVA Environment

Set the JAVA_HOME environment variable to point to the base directory location where Java is installed on your machine. For example −

OS Output
Windows Set the environment variable JAVA_HOME to C:\Program Files\Java\jdk1.7.0_60
Linux export JAVA_HOME=/usr/local/java-current
Mac export JAVA_HOME=/Library/Java/Home

Append Java compiler location to System Path.

OS Output
Windows Append the string “;C:\Program Files\Java\jdk1.7.0.60\bin” to the end of the system variable, Path.
Linux export PATH=$PATH:$JAVA_HOME/bin/
Mac not required

Verify Java Installation using java -version command as explained above.

Step 3 - Download Maven Archive

Download Maven 2.2.1 from https://maven.apache.org/download.cgi.

OS Archive name
Windows apache-maven-3.3.1-bin.zip
Linux apache-maven-3.3.1-bin.tar.gz
Mac apache-maven-3.3.1-bin.tar.gz

Step 4 - Extract the Maven Archive

Extract the archive, to the directory you wish to install Maven 3.3.1. The subdirectory apache-maven-3.3.1 will be created from the archive.

OS Location (can be different based on your installation)
Windows C:\Program Files\Apache Software Foundation\apache-maven-3.3.1
Linux /usr/local/apache-maven
Mac /usr/local/apache-maven

Step 5 - Set Maven Environment Variables

Add M2_HOME, M2, MAVEN_OPTS to environment variables.

OS Output
Windows

Set the environment variables using system properties.

M2_HOME=C:\Program Files\Apache Software Foundation\apache-maven-3.3.1 M2=%M2_HOME%\bin MAVEN_OPTS=-Xms256m -Xmx512m

Linux

Open command terminal and set environment variables.

export M2_HOME=/usr/local/apache-maven/apache-maven-3.3.1 export M2=$M2_HOME/bin

export MAVEN_OPTS=-Xms256m -Xmx512m

Mac

Open command terminal and set environment variables.

export M2_HOME=/usr/local/apache-maven/apache-maven-3.3.1

export M2=$M2_HOME/bin

export MAVEN_OPTS=-Xms256m -Xmx512m

Step 6 - Add Maven bin Directory Location to System Path

Now append M2 variable to System Path.

OS Output
Windows Append the string ;%M2% to the end of the system variable, Path.
Linux export PATH=$M2:$PATH
Mac export PATH=$M2:$PATH

Step 7 - Verify Maven Installation

Now open console and execute the following mvn command.

OS Task Command
Windows Open Command Console c:\> mvn --version
Linux Open Command Terminal $ mvn --version
Mac Open Terminal machine:~ joseph$ mvn --version

Finally, verify the output of the above commands, which should be as follows −

OS Output
Windows

Apache Maven 3.3.1 (r801777; 2009-08-07 00:46:01+0530)

Java version: 1.7.0_60

Java home: C:\Program Files\Java\jdk1.7.0_60 \jre

Linux

Java version: 1.7.0_60

Java home: C:\Program Files\Java\jdk1.7.0_60 \jre

Mac

Java version: 1.7.0_60

Java home: C:\Program Files\Java\jdk1.7.0_60 \jre
