How to run maven project in Google App Engine

I follow this guide: http://software.danielwatrous.com/wordpress-plugin-licensing-wicket-on-google-app-engine/ . I am adding the Google engine library for this project, and then I want to check the Google engine. But when I do this eclipse, this problem arises:

The App Engine SDK '/home/hudi/program/git/tournamenSystem/tournament-system/
tournament-system-web/src/main/webapp/WEB-INF/lib/appengine-api-1.0-sdk-1.7.1.jar'
on the project build path is not valid (SDK location '/home/hudi/program/git/
tournamenSystem/tournament-system/tournament-system-web/src/main/webapp/WEB-INF/
lib/appengine-api-1.0-sdk-1.7.1.jar' is not a directory)

I do not understand. Jar isnt directory, so why do we need some directory? When I want to use a quick fix, I can just use a different SDK. I try to use an older version 1.6 ... but still the same problem. How can i fix this? Please, help

On my computer with Ubuntu 12.04 and Eclipse Juno SR1, I simply move all the maven dependencies to the Java build path list button.

For an open way to create a Java template, right-click on the project - preferences - Java build path - Order and Export - select all the lines with M2_REPO (or something else) and click the "Bottom" - Update Project button. This help is needed.

Thank!
