Failed to create multi-version API

[linglingye001]

I have followed the tutorial https://book.kubebuilder.io/multiversion-tutorial/tutorial to create multi-version API. In my project, current API version is v1beta1. I want to create v1 version API but failed.

kubebuilder create api --group test --version v1 --kind testCR

This seems related to kubebuilder not controller-tools.

Hi @sbueringer, @linglingye001,

This issue is solved already.

However, go/v3 has been deprecated for an extended period and will no longer be supported after the next bump of k8s.
Therefore, the fix was applied ONLY to go/v4. More info: #3622

See: #3373

PRs:

• 🐛 (go/v4): Scaffold when no boilerplate file #3378
• 🐛: (go/v4) Scaffold no header when lincense is type none #3391

Workaround
You can create the hack/boilerplate.go.txt manually for no longer face this one such as: https://github.com/kubernetes-sigs/kubebuilder/blob/master/testdata/project-v3/hack/boilerplate.go.txt

Therefore, I am closing this one as sorted.
Thank you for raising it 🎉
