Hi,

I found this tool last week and gave it a try. It seems to fill exactly the 
gap in my CI tool chain.

I have two main problems in my current jenkins CI setup:

1. Dependencies for downstream projects need to be copied into the next job 
or need to be uploaded into an http server dir. Some selfmade tools need to 
clean up the server from time to time. Nexus Unzip is not very helpfull 
because it is (maybe was) too buggy and not every build creates a 
deployable p2 repository.

2. Bringing third party libs (mostly from maven central) into the tycho 
build is not as easy as it should be. Especially for artifacts that have 
already OSGi metadata.

Both requirements are covered by package drone quite well. It should not 
cover the whole maven central but with some clicks I could import any 
library into a project specific third party p2 repository (including a self 
generating feature).

Conclusion: I would recommend every tycho user to have a look at package 
drone or just watch the demo on youtube: https://www.youtube.com/watch?
v=kUJ5SWfAuxU (the current version has some more features)

Best regards,
Cornelius
