hibernate-validator can't find built-in constraint

[ghost]

I have a Quarkus app using resteasy-reactive and I'm trying to introduce bean validation to validate the request body. I've decorated the mapped POJOs with constraint annotations and added the @Valid annotation to the corresponding argument on the request method. I'm getting exceptions like this:

Request failed: javax.validation.UnexpectedTypeException: HV000030: No validator could be found for constraint 'javax.validation.constraints.NotNull' validating type 'java.lang.String'. Check configuration for 'method.argument.field'

Just wanted to check if this is a known issue before I create a reproducer...

Hmmm, no, it should work out of the box. Are your mapped POJOs in the Jandex index (i.e. are they part of your main app or if not do you add them to the index)?

clean process-classes quarkus:dev should be enough.

Sure, but remembering process-classes is the tricky part 😛

Also, I'm wondering what happens during development reloads. Will new indexes get created if classes are changed/added?

Does adding a empty beans.xml file in the resource directory of the module containing the pogo fix the issue?

No, it does not.

No, it does not.

Are you sure about that? That would be a bug.

Just to clarify, it should be META-INF/beans.xml

Ah, right. I've been out of practice! It does work if I add META-INF/beans.xml.

Yes, in fact, in dev mode and tests we are re-generating the Jandex indexes for local projects anyway to make sure they are up-to-date.

Okay, so just to wrap this up, the solution to my problem is to ensure that the module containing the validated POJOs is properly available to the bean discovery mechanism.

A related question about whether quarkuss:dev should imply process-classes in addition to compile remains open. (FWIW, I think it should!)

Thanks for the help everyone!

@evc-erik would you mind creating an issue to cover process-classes in quarkus:dev? Thanks.

@aloubyansky I created #22807
