When launching a Quarkus app simply using mvn quarkus:dev
, the running application is configured to open port 5005
for remote debugging.
That means that all you have to do is point your remote debugger to that port and you will be able to debug it in your favorite IDE/lightweight editor.
If however you would like to be able to suspend the application until a debugger is connected then simply execute:
mvn quarkus:dev -Dsuspend
The same port is used (5005
) but this time the application doesn’t start until a remote debugger is connected. You can use -Ddebug
to change the debugging port.
UPDATE
As of version 2020.3, IntelliJ Ultimate should recognize a quarkus application and automatically create a launch configuration that uses quarkus:dev
under the hood.
