At the moment there is no RPM package or yum install available for the latest version of Maven on Centos. The user is left to install Maven manually. To attempt to overcome this, I created a script to install the latest, at the moment: 3.1.1. At the moment, there are many things that should be added to the script, they’re listed in the TODO section of the documentation, but those features may be added later.
Instructions on how to run the script, and the script it’s self may be found at: https://github.com/monksy/centos-maven-install
