　　Step 1
Go to the Run/External Tools/External Tools ..." menu item on the "Run"menu bar. Select "Program" and click the "New" button. On the "Main"tab, fill in the "Location:" as the full path to your "mvn" executable.For the "Working Directory:" select the workspace that matches yourwebapp. For "Arguments:" add jetty:run.
　　Move to the "Environment" tab and click the "New" button to add a new variable named MAVEN_OPTSwith the value:
　　-Xdebug -Xnoagent -Djava.compiler=NONE -Xrunjdwp:transport=dt_socket,address=4000,server=y,suspend=y
　　If you supply suspend=n instead of suspend=y you can startimmediately without running the debugger and launch the debugger atanytime you really wish to debug.
　　Step 2
　　Then, pull up the "Run/Debug/Debug ..." menu item and select "RemoteJava Application" and click the "New" button. Fill in the dialog byselecting your webapp project for the "Project:" field, and ensure youare using the same port number as you specified in the address=property above.
　　Now all you need to do is to Run/External Tools and select the nameof the maven tool setup you created in step 1 to start the plugin andthen Run/Debug and select the name of the debug setup you setup instep2.

　　Stopping Jetty
　　In order to stop the jetty server the "Allow termination of remoteVM" should be checked in debug dialog in Step 2. When you have thejetty server running and the debugger connected you can switch to thedebug perspective. In the debug view, right click on the JavaHotSpot(TM) Client VM[localhost:4000] and  chose terminate. This willstop the debugger and the jetty server.
