I have installed Camel plugin for IntelliJ.
To start debugging, we must create an ad-hoc application
How do you know exactly at what port application is locally loaded? How can I change it? I have found no configurations about...
You do not need to provide a port. The debugger is attaching directly to the application using its pid. You need to be sure that the camel-debug dependency is added. I recommened to add it through a profile like shown here https://github.com/apache/camel-examples/blob/d1e5022bb1b43565903359aefaf91bcf23fc9c78/examples/main/pom.xml#L105-L120
Please note that you need a recent version of Camel (3.16 I think)
