   Thank you very much! I’m a Maven newbie and I was missing the attachClasses feature of the war plugin.

   Thank you for the pointer. Probably things have changed since v. 2.1-beta-1 of plugin, but Maven kept reporting to me from my dependent project that classes were not found unless I added the “classesClassifier” element to the referenced war project with the “classes” value (in the “configuration” section next to “attachClasses”)

   <plugin>
     <artifactId>maven-war-plugin</artifactId>
     <version>2.1.1</version>
     <configuration>
       <attachClasses>true</attachClasses>
       <classesClassifier>classes</classesClassifier>
     </configuration>
   </plugin>

      Maybe you could try using the webResources parameter. It helps you to include resource files into the WEB-INF/classes.

      i am not sure as i haven’t tried that before. but i guess it should work in Maven 1.x as i found the war plugin name in the Maven 1.x project page.

   Thanks very much for this.

   I was struggling with the appfuse warpath plugin for a while, but this approach with the war plugin is perfect and works with m2e as well.
