Java Model Generation Failed due to error message "The CustomResourceDefinition "xxx" is invalid: metadata.annotations: Too long: must have at most 262144 bytes"

[hippoz]

Describe the bug
Java Model Generation Failed due to the following error:

The CustomResourceDefinition "fleets.agones.dev" is invalid: metadata.annotations: Too long: must have at most 262144 bytes

Client Version
e.g. 1.25.1

Kubernetes Version
e.g. 1.25.1

Java Version
e.g. Java 11

To Reproduce
This bug is about crd-model-gen

Version: 1.06, 1.05 and 1.04

Steps to reproduce the behavior:

• download the long CRD definitions (more than 262144 characters), eg: the attached CRD from agones
  fleets.agones.dev.yaml.zip
• try to generate the Java models following the approach CRD Generation
• You will see this error

Expected behavior
The models can be generated successfully for long CRD definitions

Workaround
We can workaround this issue by remove all the descriptions from the CRD to make it shorter, but we lost all the java docs after the generation.

KubeConfig
If applicable, add a KubeConfig file with secrets redacted.

Server (please complete the following information):

• OS: Linux
• Environment [e.g. container]
• Cloud [e.g. Azure]

Additional context
Add any other context about the problem here.

This issue can be fixed by updating

kubectl apply -f "$url"

from kubectl apply -f "$url" to kubectl create -f "$url"

Also hit this issue, not sure if the image has the latest generate script?

Also seems like the default image should move to ghcr.io/kubernetes-client/java/crd-model-gen to align with documentation https://github.com/kubernetes-client/java/blob/master/docs/generate-model-from-third-party-resources.md
