Make manifests is not working when only the controller is scaffolded by the create api

[camilamacedo86]

What broke

After creating a project and scaffold just the controller the make manifests target will fail :

• kubebuilder int or kubebuilder init --plugins=go/v3-alpha
• $ kubebuilder create api --group ship --version v1beta1 --kind Frigate

Create Resource [y/n]
n
Create Controller [y/n]
y

What did you expect to happen? What do you think went wrong?

The controller-gen is falling with the files scaffolded in this scenario:

Users/camilamacedo/go/bin/controller-gen object:headerFile="hack/boilerplate.go.txt" paths="./..."
main.go:33:2: package testv2/api/v1beta1 is not in GOROOT (/usr/local/go/src/testv2/api/v1beta1)
Error: not all generators ran successfully
run `controller-gen object:headerFile=hack/boilerplate.go.txt paths=./... -w` to see all available markers, or `controller-gen object:headerFile=hack/boilerplate.go.txt paths=./... -h` for usage
make: *** [Makefile:62: generate] Error 1
