Until now, bundles who were merely aggregating artifacts had to

1. use packaging:jar
2. set

     <properties>
       <defaultAssemblyDescriptor>simple-assembly-descriptor</defaultAssemblyDescriptor>
     </properties>
   

   .. to

3. get the appropriate README and other .TXT files
4. use this specific assembly descriptor to avoid the empty jar to be bundled.

Once this issue is solved, such bundles will be able to set their packaging to pom and use the default assembly (module-assembly-descriptor, which is used by default when the assembly plugin is enabled, so the property definition can be removed from the bundle's pom too)
