Jack, maven-jetty-plugin belongs to the group org.mortbay.jetty, not org.apache.maven.plugins. This makes me suspect that your jetty plugin isn't configured properly.
A minimal jetty plugin configuration would look like this: <plugin> <groupId>org.mortbay.jetty</groupId> <artifactId>maven-jetty-plugin</artifactId> <configuration> <contextPath>/</contextPath> </configuration> </plugin> Could you please ensure this config under build -> plugin section in your pom.xml and retry?
