Cannot import github.com/containerd/containerd/api/runtime/v2/task

Description

When I import "github.com/containerd/containerd/api/runtime/v2/task" from my local go program, I encounter the following build error.

main.go:6:2: no required module provides package github.com/containerd/containerd/api/runtime/v2/task; to add it:
	go get github.com/containerd/containerd/api/runtime/v2/task

Then, go get github.com/containerd/containerd/api/runtime/v2/task shows the following error.

go: module github.com/containerd/containerd/api@upgrade found (v1.6.0-beta.3), but does not contain package github.com/containerd/containerd/api/runtime/v2/task

go mod tidy also shows a similar error as described later.

The api package was a Go module at v1.6.0-beta.3, and the resository has a git tag api/v1.6.0-beta.3, but the api package is not a Go module at v1.7.2, since go.mod has been remove from the api directory.

I guess that go get command first tries to find the latest version of api module, and finds the git tag api/v1.6.0-beta.3, but the old api module does not include the task directory, which was introduced in the later version.

Steps to reproduce the issue

1. Prepare go.mod

go mod init
go get github.com/containerd/containerd/[email protected]

2. Create a main.go as follows in an empty directory.

package main

import (
	"fmt"

	task "github.com/containerd/containerd/api/runtime/v2"
)

func main() {
	var t task.TaskService
	fmt.Println(t)
}

3. Update go.mod

go mod tidy

t := &task.Task{}

There is no Task structure in github.com/containerd/containerd/api/runtime/v2/task. Use a structure that exists to make the go mod tidy work.
->

t := &task.StartRequest{}
// or
var t task.TaskService

@Iceber Thank you for pointing it out. I updated my comment to correct it.

The problem still persists even after I corrected the code.

@Iceber Sorry, I used a wrong import path.

After I fixed the import path, the problem disappeared.
