When attempting to install the Maven plugin for Eclipse (m2eclipse) from the following location…
…I was encountering the following error:
Missing requirement: Maven Integration for Eclipse (Editors) 220.127.116.1120903-1050 (org.eclipse.m2e.editor 18.104.22.16820903-1050) requires 'bundle org.eclipse.wst.sse.core 0.0.0' but it could not be found
To solve this, return to the Install New Software window and add http://download.eclipse.org/releases/indigo as a software site.
At this point, you should now be able to install the Maven plugin at the next attempt.
