Edit your pom.xml file and set the scanIntervalSeconds param to 0, this will turn off Jetty's internal reloading. It should look like this:
<plugin>
  <groupId>org.mortbay.jetty</groupId>
  <artifactId>jetty-maven-plugin</artifactId>
  <configuration>
    <scanIntervalSeconds>0</scanIntervalSeconds>
  </configuration>
</plugin>

Add the following line to the MAVEN_OPTS environment variable:

-javaagent:$AGENT_PATH_WIN

To do it in the console:

  > set MAVEN_OPTS=-javaagent:$AGENT_PATH_WIN %MAVEN_OPTS%
  > mvn jetty:run
