Configuring
Step 1: Configure JVM debug mode
In mvn.bat file, remove REM from the following line:
@REM set MAVEN_OPTS=-Xdebug -Xnoagent -Djava.compiler=NONE -Xrunjdwp:transport=dt_socket,server=y,suspend=y,address=8000

Supplying suspend=n instead of suspend=y allows you to start jetty without debugger. Then, you can launch it when you want.

Step 1 bis
In the maven bin directory, you can create a command file named jetty.bat with the following lines

@set MAVEN_OPTS=-Xdebug -Xnoagent -Djava.compiler=NONE -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=8000
mvn clean jetty:run

Step 2: Configure Remote Application in Eclipse
Run/Debug…/Remote Application, right click, new and OK

Lauching
Step 1: Launch jetty in debug mode
By launching the following command in a command window:
mvn clean jetty:run

Step 1bis:
By launching the following command in a command window:
jetty

Step 2: Launch debugger in Eclipse
Launch Remote Application in debug mode

That’s all !
