Error installing Maven Integration for Eclipse WTP

Question

I am trying to install the gwt-maven-plugin for Eclipse Indigo 3.7.2 (running on Ubuntu), following the instructions here: http://uptick.com.au/content/getting-started-gwt-maven-and-eclipse

However, when I get to the step to install "Maven Integration for Eclipse WTP", I get the following error:

Cannot complete the install because one or more required items could not be found. Software being installed: Maven Integration for WTP (Optional) 0.12.0.20110421-1500 (org.maven.ide.eclipse.wtp.feature.feature.group 0.12.0.20110421-1500) Missing requirement: Maven Integration for WTP (Optional) 0.12.0.20110421-1500 (org.maven.ide.eclipse.wtp.feature.feature.group 0.12.0.20110421-1500) requires 'org.maven.ide.eclipse.feature.feature.group [0.10.0,1.0.0)' but it could not be found

A similar question on SO suggests to tick the "contact all update sites", but this isn't working for me. I have also added the Galileo & Helios update sites (in addition to Indigo) per a suggestion on this thread: http://www.eclipse.org/forums/index.php/t/206143/

Any other ideas how to resolve this?

I believe m2eclipse has moved to eclipse.org as m2e, with a new update site at http://download.eclipse.org/technology/m2e/releases/ and the newer Maven Integration for WTP (Incubation) feature from http://download.eclipse.org/m2e-wtp/releases/ . Try those.
