Jetty core components are at eclipse from jetty-7 and later.
See http://wiki.eclipse.org/Jetty/Contributor/Releasing for how to build the core components.
The jetty-7 components for jetty-maven-plugin, jetty-runner, example-async-rest-webapp, as
well as rpm, deb packaging remain at codehaus and this page will soon contain instructions
for building them.
