Java generator from CRD: class not found in quarkus when enabling extraAnnotations

[spike83]

Describe the bug

When generating Java classes from CRD within Quarkus I get ClassNotFound Exceptions.

I was playing around with annotation processing settings but nothing helped.

Every time I enable the extraAnnotations I get exceptions when executing. It is also taking way longer to generate and I even generates the class io/fabric8/kubernetes/api/model/ObjectMetaBuilder that was not found in the target folder.

Fabric8 Kubernetes Client version

7.0.0, 6.13.14

test-crd.yaml: I took one of the PrinterColmn from the tests. But it doesn't matter.

src/test/java/MyTest.java:

import org.junit.jupiter.api.Test;

import io.fabric8.kubernetes.client.KubernetesClient;
import io.quarkus.test.junit.QuarkusTest;
import jakarta.inject.Inject;

@QuarkusTest
public class MyTest {
    @Inject
    private KubernetesClient kubernetesClient;
    
    @Test
    public void test() {
        System.out.println("pod list:");
        var pods = this.kubernetesClient.pods().list();
        pods.getItems().forEach(pod -> {
            System.out.println(pod.getMetadata().getName());
        });
    }
}

mvn clean test

This causes

And it seems the class was even generated

Expected behavior

I would think that I can generate the code and run the kubernetes client afterwards.

Runtime

Kubernetes (vanilla)

Kubernetes API Server version

1.25.3@latest

Environment

Linux
