       Body:
You need to run:  maven jar  in the root jelly directory first.   

Then you need to enter the jelly/jelly-tags/swing directory before issuing: maven demo:swing

PS: The docs suck.

Somehow this doesn't surprise me:
how shall maven learn about example.jelly (albeit it is in the current working directory from
which I started maven...) - there is no "-f" option or alike where I had to tell maven where
to look for it...

Any hints would be highly appreciated - many thanks in advance!

P.S.: I am getting a similar error when just calling "maven" on its own - perhaps there is
another cause for the problem (http://jira.codehaus.org/secure/ViewIssue.jspa?key=MAVEN-427)?
