Hello everybody,

we are successfully using Package Drone, but run into a severe problem now. One of our Eclipse Features build with Maven/Tycho contains root files, which are later copied into the root directory of the final Eclipse Product, also build by Maven/Tycho in a separate step. We are using the Eclipse PDE Rootfiles strategy which is also directly supported by Maven/Tycho. Whenever we create an individual p2 repository with Maven/Tycho using the "eclipse-repository" packaging type, deploy that p2 repository to an HTTP-Server, and consume the feature with root files from there in the separate Maven/Tycho Eclipse Product build, everything works fine. However, when just deploying the feature with root files to Package Drone and consuming it from there, the build fails with the following error message:

[ERROR] The following artifacts could not be downloaded:

Maven/Tycho cannot resolve the binary artifact containing the root files of the feature. Since exactly that works with a separate p2 repository built by Maven/Tycho and hosted on a HTTP-server, I assume this is a problem introduced by Package Drone. After uploading the feature with root files, I can see the following artifacts in Package Drone:

de.vitasystems.platform.feature-2.0.0-20160108.073646-1.jar
de.vitasystems.platform.feature-2.0.0-20160108.073646-1.pom

|-- de.vitasystems.platform.feature-2.0.0-20160108.073646-1-root.zip

The de.vitasystems.platform.feature-2.0.0-20160108.073646-1-p2artifacts.xml looks as follows:

<?artifactRepository version='1.1.0'?>
<artifacts size="2">

And the de.vitasystems.platform.feature-2.0.0-20160108.073646-1-p2metadata.xml looks as follows:

What can be noticed is that the de.vitasystems.platform.feature_root artifact is correctly referenced with its OSGi version and qualifier. However, it seems to have problems resolving that artifact in Package Drone with the timestamp replacing the -SNAPSHOT qualifier of the Maven world.

Do you guys have any idea how to solve that problem? Any hints are welcome.

Regards
Timo
