CRD generator doesn't respect Jackson serialization/deserialization

Describe the bug

Having a Java class that defines:

    private String myTest = null;

    public String getTest() {
        return myTest;
    }

generates a CRD with the following:

              myTest:
                type: string

But when trying to read a corresponding CR from Kubernetes fails with the following:

com.fasterxml.jackson.databind.exc.UnrecognizedPropertyException: Unrecognized field "myTest" , not marked as ignorable

Fabric8 Kubernetes Client version

5.10.1@latest

Steps to reproduce

Try to read a CR using the kubernetes-client where the Jackson serialization have a mismatch with the name of the fields.

The viable workaround is to annotate the field to respect the generate CRD name e.g.:

    @JsonProperty("myTest")
    private String myTest = null;

    public String getTest() {
        return myTest;
    }

Expected behavior

The generated CRD should respect the Jackson serialization/deserialization informations.

In general it should be possible to have a clean round-trip for arbitrary Java classes:

Java -> CRD -> CR in Kubernetes -> client reads the CR

Runtime

Kubernetes (vanilla), other (please specify in additional context)

Kubernetes API Server version

1.22.3@latest

Environment

Linux, other (please specify in additional context)

[andreaTP]

It only creates one property. I agree that using JsonProperty annotation makes the intent much clearer.

I think that the available workaround make this issue pretty low in priority, I opened it mostly for tracking purposes.

I believe that we should somehow document what the generator takes in consideration (currently JsonProperty, JsonPropertyDescription and NotNull) so that we settle the right expectations.
