In order to contribute a open source project autojump, I clone it into my daily repo. When I staged it, the adding embedded git repository warning appears:
git add Open\ source/github.com
warning: adding embedded git repository: Open source/github.com/hustnzj/autojump
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> Open source/github.com/hustnzj/autojump
hint:
hint: If you added this path by mistake, you can remove it from the
hint: index with:
hint:
hint: git rm --cached Open source/github.com/hustnzj/autojump
hint:
hint: See "git help submodule" for more information.
The warning tip is pronounced so the solution is simple:
$ git rm --cached Open\ source/github.com -r
$ git submodule add https://github.com/hustnzj/autojump Open\ source/github.com/hustnzj/autojump
Adding existing repo at 'Open source/github.com/hustnzj/autojump' to the index
$ git status
On branch daily
Changes to be committed:
(use "git restore --staged <file>..." to unstage)
modified: .gitmodules
new file: Open source/github.com/hustnzj/autojump
$ git commit -m 'Open source contribution: autojump'
