• Automatically open and expose --debug-port=PORT for debugging with a Java IDE (IDEA, for example)

$ git clone https://github.com/dhis2/dhis2-core
$ git checkout v2.37.10 # version to debug, it should match the WAR version

As discussed with Arnau, I am unable to debug due to an issue specific to MAC M1 machine. I will try to debug further at a later time, but do not want to block the merging of this PR.

Tested with data docker.eyeseetea.com/eyeseetea/dhis2-data:2.37.9-sierra and docker.eyeseetea.com/eyeseetea/dhis2-data:2.37.10-test both with options --core-image=docker.eyeseetea.com/eyeseetea/dhis2-core:2.37.10 --debug-port=7080. All the docker part is correct, but when I configure the debugger in IntelliJ I get the following error:

Tested in Ubuntu 22.04.3 LTS

I see what's happening. Depending on the JDK version, the debug port listens to all or only localhost, that's why it was core-dependent. ea876a0: Now it's forcing a binding to 0.0.0.0 so it should work for any core.

Can you test again? @9sneha-n @anagperal

(No need to regenerate the cores)

@tokland I am still getting the same error :(

Hi! For me, it's already working. Thanks!

Cool! So maybe Sneha is still stuck with the Mac-specific problem. We'll check it out, anyway.

The debug port works for me too! thank you @tokland for taking time to figure out the issue :D

@eperedo Can you test the current version in Windows?

[eperedo]

@tokland Sorry, I didn't have time to test it again. I'll try to do it as soon as possible.

UPDATE: working on windows 10

• To avoid exposing random debug port if not specified -> refactor: generate dynamic yaml + use to remove debug-port reference if empty
