Re: [cross-project-issues-dev] p2 repositories ... we can do better

[Jesse McConnell <jesse.mcconnell@xxxxxxxxx>]

Not sure for tycho but given some time I could have that in the
signing plugin in an hour or so I would think.

I'll see if I can scrape some time together to get that support added
in, at least in the interm until tycho could support it

cheers,
jesse

As last means of resort I'll write a bash script that unzips artifacs.jar, adds the property to the artifacts.xml, and zips the file again.
