31 * This goal is used to assemble your webapp into a war and automatically deploy it to Jetty.
32 * </p>
33 * <p>
34 * Once invoked, the plugin can be configured to run continuously, scanning for changes in the project and to the
35 * war file and automatically performing a
36 * hot redeploy when necessary.
37 * </p>
38 * <p>
39 * You may also specify the location of a jetty.xml file whose contents will be applied before any plugin configuration.
40 * This can be used, for example, to deploy a static webapp that is not part of your maven build.
41 * </p>
42 * <p>
43 * There is a <a href="run-war-mojo.html">reference guide</a> to the configuration parameters for this plugin, and more detailed information
44 * with examples in the <a href="http://docs.codehaus.org/display/JETTY/Maven+Jetty+Plugin/">Configuration Guide</a>.
