Golang中的版本控制第三方软件包

Question

I am using third party packages in golang and I want to add them to my git repository and when I type the command git add . it is giving me the following error

warning: adding embedded git repository: github.com/beorn7/perks
hint: You've added another git repository inside your current repository.
hint: Clones of the outer repository will not contain the contents of
hint: the embedded repository and will not know how to obtain it.
hint: If you meant to add a submodule, use:
hint: 
hint:   git submodule add <url> github.com/beorn7/perks
hint: 
hint: If you added this path by mistake, you can remove it from the
hint: index with:
hint: 
hint:   git rm --cached github.com/beorn7/perks
hint: 

How to make sure that I am version controlling packages correctly and Am I doing the right way of version controlling my third-party packages?

Here is my project structure

Project/
|
src/
  |
   github.com/
      |
      packages/

My GOPATH is also pointing to project directory

Answer 1

From what I understand you don't use any package manager, instead you import packages to your $GOPATH. I would advise you to use package manager like dep which builds vendor directory containing all dependencies. When you run dep ensure it will go through your code and pull all the dependencies automatically.

Edit: As @jubobs since go1.11 you can use go mod. Basic premise is the same as dep.
