Getting compilation error when try to use kubernetes/fake from "production" code. however when create test and use fake from there only then everything is good and test compilation is not failing.

compilation error:

cmd\test\test.go:3:8: cannot find package

project structure

awesomeProject
│   go.mod
│   go.sum
└───cmd
    └───test
            test.go

here is test.go

package main

import "k8s.io/client-go/kubernetes/fake"

func main() {
    clientset := fake.NewSimpleClientset()
    print(clientset)
}

here is go.mod (updated to have same version of api + goclient)

module awesomeProject

go 1.14

This question is coming from need to move kubernetes/fake related code to separate package from test code.
