SDKs removed from class path by maven GWT plugin

[svanhook]

I converted my eclipse GWT project to a maven built project.
Eclipse is now giving me three errors:
"TestProject does not have any App Engine SDK's on its build path"
"TestProject does not have any GWT SDK's on its build path"
"The output directory for the project should be set to /TestProject/
war/WEB-INF/classes"

How can I have maven pull in these sdk's into the .classpath file and
how can I resolve the output directory issue.
Thanks

This has nothing to do with GWT-Maven, and GWT-Maven has nothing to do
with Eclipse. Sorry, but can't help with this type of issue. The
Codehaus plugin has some Eclipse integration, you might try that one
(if you haven't already - this is a very late response).
