I think I know what is happening. The maven-jetty-plugin has been
moved. It is now the jetty-maven-plugin. I reran the
archetype:generate with a new artifactId and before running the mvn
jetty:run I edited the pom to contain the following:
<plugin>
<groupId>org.mortbay.jetty</groupId>
<artifactId>jetty-maven-plugin</artifactId>
<configuration>
<scanIntervalSeconds>5</scanIntervalSeconds>
</configuration>
</plugin>
NOTE that I also had to remove the configuration for the contextPath
because jetty was saying that it could not override readonly
configuration parameter.
I tried to post this earlier so I hope this works and that it is not a
duplicate.
