Hi,
If you're experiencing problems with Maven and the Jetty lib then, what's helped me (thanks Jan from Mort Bay for the hint) was to upgrade Maven to 1.0.1 version. I remember I was struggling with the issue of downloading the lib while building Geronimo online for a long time, and suspect there're others who suffer from it. I guess it was something with the locale. During the Geronimo build the downloaded Jetty jar was of 0 bytes in size and the build couldn't finish without a human intervention.
