为什么代码中的某些软件包以v2为前缀，但是我克隆的文件路径没有v2？

Question

GitHub:https://github.com/filebrowser/filebrowser

When I read the source code of this project, I found that main.go relied on the cmd package. I found that the path in the import statement contains v2, but I have no v2 in the file path after I cloned the project from github? why is this happening?

package main

import (
    "runtime"

    "github.com/filebrowser/filebrowser/v2/cmd"
)

func main() {
    runtime.GOMAXPROCS(runtime.NumCPU())
    cmd.Execute()
}

The structure of this project

Answer 1

The github.com/filebrowser/filebrowser repository is using the “major branch” style of code layout, which puts the v2 variant of the module on a branch or v2.X.Y tag rather than in a subdirectory.
