go - Glide 或 dep 依赖问题，vendor 中的依赖不平坦

Question

相关代码如下:

import (
    core "k8s.io/api/core/v1"
    metav1 "k8s.io/apimachinery/pkg/apis/meta/v1"
    "k8s.io/kubernetes/pkg/api/legacyscheme"
)
...

func PodExec(clusterId string, namespace string, podName string, containerName string, cmd string) (){

    ...

    req.VersionedParams(&core.PodExecOptions{
        Container: containerName,
        Command:   []string{"bash", "-c", cmd},
        Stdin:     false,
        Stdout:    true,
        Stderr:    true,
        TTY:       false,
    }, legacyscheme.ParameterCodec) //FIXME Here is the concerned code.

}

...

glide.yaml如下:

package: xxx-k8s-apiserver
import:
- package: github.com/astaxie/beego
  version: v1.10.1
- package: k8s.io/api
  subpackages:
  - apps/v1
  - core/v1
- package: k8s.io/apimachinery
  subpackages:
  - pkg/api/errors
  - pkg/api/resource
  - pkg/apis/meta/v1
  - pkg/util/intstr
  - pkg/util/yaml
- package: k8s.io/client-go
  version: v10.0.0

当我在我的项目中运行 go build 时，出现这样的错误。

# xxx-k8s-apiserver/models
models/pod.go:82:3: cannot use legacyscheme.ParameterCodec (type "xxx-k8s-apiserver/vendor/k8s.io/kubernetes/vendor/k8s.io/apimachinery/pkg/runtime".ParameterCodec) as type "xxx-k8s-apiserver/vendor/k8s.io/apimachinery/pkg/runtime".ParameterCodec in argument to req.VersionedParams:
        "xxx-k8s-apiserver/vendor/k8s.io/kubernetes/vendor/k8s.io/apimachinery/pkg/runtime".ParameterCodec does not implement "xxx-k8s-apiserver/vendor/k8s.io/apimachinery/pkg/runtime".ParameterCodec (wrong type for DecodeParameters method)
                have DecodeParameters(url.Values, "xxx-k8s-apiserver/vendor/k8s.io/kubernetes/vendor/k8s.io/apimachinery/pkg/runtime/schema".GroupVersion, "xxx-k8s-apiserver/vendor/k8s.io/kubernetes/vendor/k8s.io/apimachinery/pkg/runtime".Object) error
                want DecodeParameters(url.Values, "xxx-k8s-apiserver/vendor/k8s.io/apimachinery/pkg/runtime/schema".GroupVersion, "xxx-k8s-apiserver/vendor/k8s.io/apimachinery/pkg/runtime".Object) error

然后我看到 ./vendor 目录，似乎 glide 或 dep 以某种方式错误地组织了依赖路径。依赖关系并不平坦，因为 vendor 路径 ./vendor/k8s.io/kubernetes/vendor 中还有另一个 vendor。

How to handle nested "vendor" directories in Go packages?

典型的嵌套 vendor 问题。仍然不知道为什么 --strip-vendor 在 glide install 中默认不是 true，这会造成很多不便。

这是一个重复的问题。
