Bumping to Quarkus 3.18.x or 3.19.x causes exception of "Couldn't instantiate DependentResource"

[gonmmarques]

For context, i'm currently running Quarkus 3.17.8 and Kotlin 2.0.21. Also using Quarkus Operator SDK (version defined via the Quarkus Platform).

I have a Reconciler with a DependentResource, and that DependentResource has a dependency that is being injected by Quarkus:

@ControllerConfiguration(
    dependents = [
        Dependent(
            type = MyDR::class
        )
    ],
)
class UserReconciler(
    private val dep: Dependency,
) : Reconciler<User>

@KubernetesDependent
@Singleton
class MyDR(
    private val dep: Dependency,
) : CRUDKubernetesDependentResource<RoleBinding, User>(RoleBinding::class.java),
    BulkDependentResource<RoleBinding, User> {

This works and has been working.

Now when upgrading to Quarkus 3.18.x or even 3.19.x (for simplification I'm using 3.19.1), I have done all the needed changes for JOSDK v5 (in the example above, use the @Workflow annotation to declare a dependent resource for example) and it is failing to start with:

Thanks in advance.

[metacosm]

This seems like a bug, indeed. Investigating. Thank you for the report and the information!

[metacosm]

It should be addressed with #1064. If you get a change to try it out, let me know if it works and I will cut a new release.

[gonmmarques]

Hey @metacosm

Thanks for the quick feedback. Sure I can try it out, is there a snapshot/R.C version artifact published that I can use to test?

[metacosm]

OK, I will merge then so that a snapshot can be deployed.

[metacosm]

The snapshot version can be found at: https://s01.oss.sonatype.org/content/repositories/snapshots/io/quarkiverse/operatorsdk/
(7.1.1-SNAPSHOT)

Hello again @metacosm

Yes, it seems to be all good now. Thanks a lot.
