Found the solution myself :-). For the record, here's what gets rid of
the warning:

> <plugin>
>   <groupId>org.eclipse.tycho</groupId>
>   <artifactId>tycho-p2-plugin</artifactId>
>   <executions>
>     <execution>
>       <!-- Don't attach (default) metadata before the source-feature execution.-->
>       <id>default-p2-metadata-default</id>
>       <configuration>
>         <attachP2Metadata>false</attachP2Metadata>
>       </configuration>
>     </execution>
>     <execution>
>       <!-- Do attach metadata after the source-feature execution.-->
>       <id>attach-p2-metadata</id>
>       <goals>
>         <goal>p2-metadata</goal>
>       </goals>
>       <phase>package</phase>
>     </execution>
>   </executions>
> </plugin>

Hope this is useful to others as well.

Best wishes,

Andreas
