I tried the demo:swing target, and it worked fine for me. This is with maven Beta 10
and CVS head of jelly.
I think it could be closed...?

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!
Ralf
P.S.: I am getting a similar error when just calling "maven" on its own - perhaps
there is another cause for the problem
