How to Get Eclipse, Maven and Google PlayN to work together?

I have tried three times now to get eclipse setup to run the playn-sample projects with no luck. I have tried the following starter guides:

http://code.google.com/p/playn/wiki/GettingStarted

http://www.gamefromscratch.com/post/2011/10/13/Getting-started-with-PlayN.aspx

And have been able to get up to the import part of the guides when I start running into issues. I have cleaned out all JRE, JDK Eclipses installs, and currently have the following installed.

Java SE SDK 6u29

Android SDK r18

Eclipse IDE for Java EE Developers

m2e - Maven Integration for Eclipse v1.0.200.20111228-1245

(from all available update sites)

Android Plugin for Eclipse ver. 18.0.0.v201203301601-306762

Google Plugin

Maven Integration for WTP ver. 0.15.2.20120306-2040

My experience starts deviating from the guides when I try to import the the playn-samples into the workspace. I keep getting the following error:

No marketplace entries found to handle android-maven-plugin:3.1.1:proguard in Eclipse. Please see Help for more information.

While I have been programming for years, my time has been in visual studio predominantly C#,ASP.NET, and in the past two years I have picked up jQuery/JavaScript. I programmed some in java back in college and saw the PlayN framework as a good reason to get back in. What am I missing from these guides to get up and running?
