For the first time in my life, I'm changing the company I work for. @RedHat -> @IBM. I think this is the best thing that could happen for my career and for @QuarkusIO, which I want to succeed.

We are standing strong, continuing our mission.

Transformation complete!

@gnahraf.bsky.social Actually, it might be only your Maven version. Quarkus needs at least Maven 3.8.6+. In the book, we recommend Maven 3.9.8+. I am able to reproduce this error on Maven <= 3.6.3.

No problem. Everything is doable, and if you show us your use case, we can always add or change some functionality if we see it makes sense in some scenarios.

Hey @tomvanwemmel.bsky.social, this is a decision made by the Kafka integrators in Quarkus. But you can opt out if you need - quarkus.io/guides/kafka.... Would that work for you?

LLMs are probably the worst thing that ever happened to conference abstracts. What is the point of writing a short article for the abstract? We can often see the LLMs' patterns. And I personally reject such proposals.

Use it LM to verify/correct, not write everything.
