Describe the bug
Since the change in how the remote-dev feature works (was that around 1.6, 1.7?), the remote dev doesn't quite work for me anymore.

Before, I've used this approach: https://blog.sebastian-daschner.com/entries/quarkus-remote-dev-in-containers

Now, I've tried the following, with mutable-jar and QUARKUS_LAUNCH_DEVMODE=true on the production side, which basically works, but results in many connection errors, and also reacts much slower than usual, since it involves some restarts (?).

To Reproduce

When I change some Java code and make another HTTP request, it produces the following errors:

In mvn:

I've used:

  • Quarkus: 1.8.1.Final
  • Java: Eclipse OpenJ9 VM AdoptOpenJDK (build openj9-0.19.0, JRE 14 Linux amd64-64-Bit Compressed References 20200318_6 (JIT enabled, AOT enabled)

With that experience, I'm blocked to update to the latest version. What is the correct way to run this new remote-dev mode?

Looking at your workflow this is not actually remote, you are running both the remote agent and the mvn quarkus:remote-dev agent in the same directory.

You need to either:

  • copy the target somewhere else and run it from there
  • put it in a container

previously the agent would just handle sending files, while now it handles local compilation as well, this causes them to both interfere with each other and weirdness results.

Sorry for responding late.

Actually, this was just the reproducer which resulted in the same condition like in the container. In my tests, it also didn't work inside a Docker container. Could you please re-open? From my PoV it's still open.

I could only reproduce problems with pom.xml changes, that I think should be fixed at #12969

I could not reproduce any problems with normal java files changes.

Can you test out the PR and let me know if it helps?
