Here are step-by-step instructions for installing/integrating Maven with Eclipse, up to date as of August 2013.
(Note: the latest version of Eclipse is Kepler, which already has Maven installed. If you are using Kepler, verify that you have it installed by going to Help => About Eclipse, and then clicking on Installation Details).
1. Go to Help => Eclipse Marketplace. Search for Maven, and select Maven Integration for Eclipse. Click Install.

2. Verify all three boxes are checked, then click Confirm.

3. When you're done, restart Eclipse.
