Hi,
I've created an XWiki plugin, which uses a whole lot of frameworks to
do it's job, including
WebObjects, ProjectWonder and some of our own frameworks. It's running
fine in Eclipse.
When I package the resulting webapp from the workspace's server area
(.metadata/.plugins/org.eclipse.wst.server.core/tmp0/wtpwebapps/xe-
debug-web)
into a war file, I can deploy the result in a webserver.
Now I would like to be able to package the xe-debug-web from the
command line
or Eclipse into a .war. However: When I invoke mvn clean package (or
any other
mvn command for that matter) inside the xe-debug-web project
directory, i get the
following error message:
mvn package :

I don't know what to do about this message. So my thought was to
create a Maven goal
in Eclipse from the run configurations. However, the 'war' goal seems
to be quite fussy
about the layout, and the xe-debug-web project layout does not to be
satisfactory:

Since both approaches failed, I need some advice on how to package the
xe-debug-web into
a proper WAR file again.
All pointers much appreciated,
J.L.Simon
