Will i have to tell maven where to find jetty and how do i install the jetty plugin?.In this version of maven,i find the plugins directory.Should there be one?.

Answer 1

Try adding the plugin in pom.xml

<plugin>
  <groupId>org.eclipse.jetty</groupId>
  <artifactId>jetty-maven-plugin</artifactId>
  <version>9.0.5.v20130815</version>
</plugin>

Answer 2

You'll need to add the plug-in to your pom.xml . Here's the documentation.
