Thanks a lot for this improvement, looks good to me, but I should ask to test the content of the newly generated fields 🙏

LGTM, @baloo42 are you planning to iterate more on this?
I think that's good to go 😄 feel free to remove it from "Draft"

- Allow to define validation rules on classes - Combine validation rules from attributes and accessor methods - Combine validation rules from inherited classes and attributes/accessor methods

@andreaTP Now I'm ready. I added support for some advanced use cases.
Please have a look at the added example and the expected result.

Now the only feature which is still missing is support for meta-annotations. But that's missing for the other annotations, too. Have you discussed the support of meta-annotations in the CRDGenerator in the past?

A couple of minor comments that should slightly simplify the PR, but looks very promising!

not sure I'm getting this one, maybe this is related: #3768

#3768 is something different. (But should be implemented too in my opinion)

With "meta-annotations" support I mean that a user is able to combine our existing annotations to new annotations like described in the following article with JUnit annotations:
https://dzone.com/articles/what-are-meta-annotations-in-java

Spring, for example has also support for Meta-Annotations/Composed Annotations:
https://docs.spring.io/spring-framework/reference/core/beans/classpath-scanning.html#beans-meta-annotations

Is this something we want to support in the future? (Is there an easy and performant way to implement it with sundrio?)

That's interesting, and it has not been discussed previously.
I encourage you to open a separate issue, and I would love to see a strawman on how we can leverage this feature.
If I understand the problem space correctly with meta-annotations we should be able to combine, for example, io.fabric8.generator.annotation.Max with org.hibernate.validator.Max and that would be a great use-case (also for the java-generator)

andreaTP

This PR LGTM, thanks again for all the help @baloo42 ! Appreciated 🙏

crd-generator/api/src/main/java/io/fabric8/crd/generator/AbstractJsonSchema.java

          facade.nullable,
          facade.required,
          facade.preserveUnknownFields);

      addProperty(possiblyRenamedProperty, builder, possiblyUpdatedSchema, options);
    }

+    List<KubernetesValidationRule> validationRules = Stream
+        .concat(definition.getAnnotations().stream(), definition.getExtendsList().stream()
+            .flatMap(classRef -> GetDefinition.of(classRef).getAnnotations().stream()))


I needed here a way to resolve annotations for inherited classes. Is this the right way to implement it with sundrio?

GetDefinition.of(classRef)

The issue has been created: #5823
Let's discuss some use cases in this issue.

(Some use-cases can be useful and can be implemented, some won't work)

LGTM, thx!
