Looking at the Hudson source code, it seems as if artifact archiving is meant to only match against files.

You might want to file a feature request or send an email to the USERS list, the Hudson team is pretty good about replying to requests and/or adding features in new releases.

sigh... Thanks Matt, I had hoped this wasn't the case but you're right

I think the better feature request would be a browser that lets you traverse the contents of a zip file artifact.

Thats not a bad idea Michael, it would help cut down on artifact size

You should create the artifact that you want in your build scripts, and then have hudson archive that file. So if you want a zip file that contains empty folders, do the appripriate zip command in your batch file or ant script. Then archive the output file.

Michael Donohue
certainly a workable idea and i'll upvote it for that, but we prefer to have hudson zip up the files on demand via "Download these files as a zip". That way we have the ability to browse the contents of the artifacts and download a single file or two if we choose to.
