Here are the steps I used to open the project in Eclipse:

- Get a local copy of the gwtgae2011 repository with this command:
   hg clone https://code.google.com/p/gwtgae2011/ gwtgae2011

- In Eclipse (Indigo) select: File -> Import... -> Maven > Existing Maven 
Projects
- Enter local path to the cloned gwtgae2011 reposity and press Next.
- Ignore errors and click on Finish

See the steps for running GWTP samples here:

I still cannot figure how to run the project from within eclipse as there is no 
"Run as Web Application" option.

Thanks I am able to add it in eclipse but I would like to run mvn 
eclipse:eclipse on the command line as well, anyone have any idea why this is 
happening?
