I'm currently working on a project which uses the maven war overlay feature. In such condition, I didn't succeed to start my a Tomcat instance from Eclipse WTP. That's because the war is built to late in the maven process and the Maven integration with WTP never calls the appropriate building step. Thus, I decided to start my server from the command line. With 'war overlay', I need to do :
mvn tomcat:run-war
But, what about debugging? Here I found two solutions.
Solution 1 : the standard mode
Just use :
mvnDebug tomcat:run-war
But it's a pre-configured solution and you should want to precise some specific options according to your environment.
Solution 2 : customize your debugging options
This is very simple.
- Ensure that you correctly declared your JAVA_HOME
- Set the debugging options which will be used by the JVM
For example :
export MAVEN_OPTS="-Xdebug -Xnoagent -Djava.compiler=NONE -Xrunjdwp:transport=dt_socket,server=y,suspend=y,address=8000"
Then, just start your server with mvn tomcat:run-war
