How to integrate maven with eclipse

I am trying to integrate maven with Eclipse and it returns the following error "Cannot complete the install because one or more required items could not be found. Software being installed: m2e - Maven Integration for Eclipse (includes Incubating components) 1.6.2.20150902-0002 (org.eclipse.m2e.feature.feature.group 1.6.2.20150902-0002)". I have tried using this URL "http://download.eclipse.org/technology/m2e/releases" and I still get the error message.

I am not sure if this can be considered as an answer. Select a Project, try to press Shift-alt-x and then after a menu appeared right corner press M. After that write "clean install" and hit enter.
