Quarkus remote DEV mode fails on 999-SNAPSHOT over `-dev` dependencies

[michalvavrik]

Describe the bug

I mentioned that Quarkus remote DEV is broken with 999-SNAPSHOT but works with 3.23.0. See #48142 and #47756 for 999-SNAPSHOT changes, I didn't check all Phillip PRs to indetify which makes the difference, I saw #45053 but that was in 3.23 so probably not causing it.

Expected behavior

Remote DEV mode works as it did with 3.23.0.

Actual behavior

Remote dev requests fail from the Quarkus DEV local process fails to connect to the remote process 2025-06-03 14:08:47,882 ERROR [io.qua.ver.htt.dep.dev.HttpRemoteDevClient] (Remote dev client thread) Remote dev request failed: java.net.SocketException: Connection reset. The remote process sports following failures:

I had a quick look, but I am not sure what the issue is. I think we are going to need @aloubyansky to help here.

[aloubyansky]

I wasn't able to reproduce it so far @michalvavrik. Do tests from RemoteDevMojoIT pass for you?

[phillip-kruger]

@aloubyansky I could reproduce it. Just followed the instructions in the issue. I had to set to ENV to true for remote dev, but the error I got guided me

[aloubyansky]

Here is the log I see on the "remote" side

You are right @phillip-kruger , I forgot to mentioned that ENV var, I have updated the reproducer, thanks.

Could you share the client logs?

which is a different (not the failure I mentioned in this issue), but that test never failed with previous Quarkus versions and I guess these log messages are related.

[aloubyansky]

I was aware of the differences between the mutable-jar and the dev mode dependency model before but I didn't see these failures previously (still wasn't able to reproduce them locally).
I think a way to align on the model would be to either introduce a remote-dev-mutable-jar (in addition to mutable-jar), which doesn't sound like a great option, or make the client use the production dependency model instead of the regular dev mode one, which will mean no dev ui and other dev features, which is probably ok for remote-dev use-case.

[aloubyansky]

I pushed the change here https://github.com/aloubyansky/quarkus/tree/remote-dev-normal-model
We probably need some more adjustments for multi module projects for which we should add tests.

[aloubyansky]

BTW, inconsistencies between mutable-jar and the dev mode dependency models were there before. The dev-only dependencies just make differences more significant.

for that diff you pasted before. I can try your new branch later today if it is different. I need to go now. Pity you can't reproduce it locally, not sure why.

[aloubyansky]

Ok, then I need another tweak there
