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 : [INFO] Scanning for projects...

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
