/kind bug

I am getting the following errors while trying to generate a new crd scaffold.

...

Versions

kubebuilder version
# Version: version.Version{KubeBuilderVersion:"2.0.0", KubernetesVendor:"1.14.1", GitCommit:"b31cc5d96dbc91749eb49c2cf600bd951a46d4bd", BuildDate:"2019-08-22T23:39:53Z", GoOs:"unknown", GoArch:"unknown"}
go version
# go version go1.13 darwin/amd64

Repro steps

1. Installed kubebuilder, kustomize per these instructions
2. Init a new project

go mod init github.com/fred/crds
kubebuilder init --domain fred

1. Create an API

kubebuilder create api --group webapp --version v1 --kind Guestbook

Results

kubebuilder create api fails with the following errors.

Usage:
  controller-gen [flags]

Examples:
    # Generate RBAC manifests and crds for all types under apis/,
    # outputting crds to /tmp/crds and everything else to stdout
    controller-gen rbac:roleName=<role name> crd paths=./apis/... output:crd:dir=/tmp/crds output:stdout

    # Generate deepcopy implementations for a particular file
    controller-gen deepcopy paths=./apis/v1beta1/some_types.go

    # Run all the generators for a given project
    controller-gen paths=./apis/...

Found the problem, my bad!
Had a stale controller-gen in my GOBIN from a previous kubebuilder install.
All generation looks good now.

Thanks, had the same problem.

[Skarlso]

so this still happened with go and kubebuilder. What did you do to fix it? I tried deleting and reinstalling things, but I'm getting the same problem @derailed?

@Skarlso , If you have controller-gen file under $GOBIN delete it and try create api again. If your $GOBIN is not set it defaults to $GOPATH/bin. Hope this helps.

Turns out I had to build the project and use that binary me self. So now it works. 😊
