The installation of Maven is just setting up Maven home in the extracted Maven folder. For ease, let's assume the maven3 folder resides in C:Program Files. Now, set Maven home with the following command in the command prompt:

set M2_HOME="c:Program Filesmaven3apache-maven-3.2.1"

Update the PATH variable as follows:

set PATH =%PATH%;%M2_HOME%in

Alternatively, the variables can be set permanently by navigating to Desktop | My Computer | Properties. Visit http://www.computerhope.com/issues/ch000549.htm for more information.

Let's assume the maven3 folder resides in the /opt folder. As Mac OS does not have the /opt folder, let's create a folder opt in root, that is, /opt. Now, let's assume we have maven3, the extracted folder in it. Then, set the Maven home by issuing the following command via the terminal:

export  M2_HOME=/opt/maven3/apache-maven-3.2.1

Add Maven to the PATH variable as follows:

export PATH=${M2_HOME}/bin:${PATH}

To add it permanently, add it to the bash file as follows:

cd $HOME
vi .bash_profile

Add the preceding variable, that is, two lines to the file, save it, and execute the following command:

source  .bash_profile

Verifying the installation of Maven

After performing the previous steps, its time to verify the installation of Maven. To verify the installation, perform the following:

• For Windows, open the command prompt and type the following:

  mvn -version
  

• For Linux and Mac OS, open the terminal and type the following:

  mvn -version
  

It should show the corresponding version of Maven installed, as shown in the following screenshot:
