"k8s.io/apimachinery/pkg/runtime".Object does not implement client.Object (missing GetAnnotations method)

[dove-young]

I generated a project as instruction here https://book.kubebuilder.io/quick-start.html#create-a-project

1. kubebuilder init --domain my.domain --repo my.domain/guestbook
2. kubebuilder create api --group webapp --version v1 --kind Guestbook
3. make manifests
4. make build
5. then add a function in api/v1/guestbook_types.go to use client.Client

func DeleteResource(cl client.Client, obj runtime.Object) error {
	deleteOption := client.DeleteOptions{}

	err := cl.Delete(context.TODO(), obj, &deleteOption)
	if err != nil {
		log.Error(err, "Failed to delete .")
	}

	return err
}

6. then go build fails

[root@myhost guestbook]# make build
/root/projects/guestbook/bin/controller-gen object:headerFile="hack/boilerplate.go.txt" paths="./..."
go fmt ./...
go vet ./...
# my.domain/guestbook/api/v1
api/v1/guestbook_types.go:78:31: cannot use obj (type "k8s.io/apimachinery/pkg/runtime".Object) as type client.Object in argument to cl.Delete:
        "k8s.io/apimachinery/pkg/runtime".Object does not implement client.Object (missing GetAnnotations method)
make: *** [Makefile:56: vet] Error 2
