Unit tests not working when upgrading Quarkus 1.11.3 to 1.12.0+

[TungstenX1]

I'm trying to update my Quakrus project from 1.11.7.Final to 1.12.x (and eventually 2.x.x), both the Quakrus core as well as the plugin. I get the following error when running mvn clean verify when I go to 1.12.x or higher:

Caused by: java.lang.IllegalArgumentException: Producer method return type not found in index: org.eclipse.microprofile.reactive.streams.operators.PublisherBuilder

I have no idea where to start looking for the problem; as the PublishBuilder seems to be in the framework and not in my code?

Any ideas of where to look or what to upgrade or add?

Can you post the full stack trace, not just the first message ?

Two more times and then:

Caused by: java.lang.IllegalArgumentException: Producer method return type not found in index: org.eclipse.microprofile.reactive.streams.operators.PublisherBuilder

I haven't seen that exact error before...

@geoand @mkouba any idea?

[geoand]

We would need an example application to run it and debug
