Build failed after godep save

[fanux]

go build success, then I godep save and go build failed:

# git.xfyun.cn/container/genesis/modules/authentication

Steps to reproduce behavior

git clone https://github.com/kubernetes/kubernetes
cp -r kubernetes $GOPATH/src/k8s.io/
cp -r kubernetes/vendor/k8s.io/* $GOPATH/src/k8s.io
rm  $GOPATH/src/k8s.io/kubernetes/.git
cd $GOPATH/src/k8s.io
git init && git add . && git commit -m add

Our project using kubernetes source code, then go build will success. then:

godep save
go build

build failed. beacuse of godep not save kubernetes:

╰─➤  ls vendor/k8s.io                                                                                               2 ↵
api          apimachinery client-go    utils

we import this: kubeadmutil "k8s.io/kubernetes/cmd/kubeadm/app/util"

godep version output

godep v80 (darwin/amd64/go1.9.2)

go version output

go version go1.9.2 darwin/amd64
