Solution

Make sure you have the Guava Libraries from Google in you classpath. There are required by the Jetty Web Server.

The Guava project contains several of Google's core libraries that we
rely on in our Java-based projects: collections, caching, primitives
support, concurrency libraries, common annotations, string processing,
I/O, and so forth.

These libraries can be downloaded from:
