multiple vendor path for same type

[Nobin Mathew]

Hi all,

I am almost new to golang, sorry if I am asking some silly question.

I am facing some compilation issue due to type conflict

I Included a library 

"github.com/k8snetworkplumbingwg/network-attachment-definition-client/pkg/client/clientset/versioned/typed/k8s.cni.cncf.io/v1"

in kubernetes (this is for some internal development, kubernetes guys wont like it :) )



if you look at line number 239:44 error, there is type conflict but it is actually pointing to same struct.
Expecting is 
"k8s.io/kubernetes/vendor/github.com/k8snetworkplumbingwg/network-attachment-definition-client/vendor/k8s.io/client-go/rest".Config"

but provided "k8s.io/kubernetes/vendor/k8s.io/client-go/rest".Config" 

But if you look at what is after "vendor", both are same i.e. "k8s.io/client-go/rest".Config"



How can I solve this problem. I any help or pointers will be helpful(any directions to read).

In Go, types are distinguished by the import path used to find the type.

In this case, it looks like you have the same package at two different
positions in your source tree. Go will treat the types defined in
those two different packages as different types.
