how to add maven plugin to eclipse

Question

I am new to maven. I was trying to add the maven plugin to eclipse(indigo). The problem I am facing is that when I try to add the plugin using 'Help -> Install new software' using URL http://download.eclipse.org/releases/indigo the download process starts and then stops with an error

An error occurred while collecting items to be installed
session context was:(profile=epp.package.jee, phase=org.eclipse.equinox.internal.p2.engine.phases.Collect, operand=, action=).

Also when I try to install the plugin using http://download.eclipse.org/technology/m2e/releases then the installation gets stuck 48% and after a long time it again displays an error message:

Kindly suggest if there is something wrong with the installation process I am using.

Also suggest if there is some other method to add 'maven plugin for eclipse'.

Thanks
