Git submodule add: "a git directory is found locally" issue

If you already deleted the submodule directory, like I did, follow the rest of jbmilgrom's instructions. The key is rm -rf .git/modules/path_to_submodule but go ahead and backup your whole parent repo directory first.

If you only had one submodule just delete .gitmodules

i tried jbmilgrom's solution, specifically i tried git rm --cache and that didn't work for me either as the directory/submodule wasn't there. What worked for me was:

1. rm -rf .git/modules/blah
2. git submodule add git://path.to.new

I did this after trying --force within the git submodule commands and rm all the other directories, pushes to master etc... the directory didn't exist and there was no reason for the cache. Turns out in .git/modules that is where this error was lying.

I came to this SO post trying to add a submodule with the same path as a submodule that I recently deleted.

This is what ultimately worked for me (this article helped out a lot):

If you haven't already run
git rm --cached path_to_submodule (no trailing slash) as well as
rm -rf path_to_submodule

Then:

1. Delete the relevant lines from the .gitmodules file. e.g. delete these:

[submodule "path_to_submodule"]
        path = path_to_submodule
        url = https://github.com/path_to_submodule

2. Delete the relevant section from .git/config. e.g. delete these:

[submodule "path_to_submodule"]
        url = https://github.com/path_to_submodule

3. rm -rf .git/modules/path_to_submodule

Then, you can finally:

git submodule add https://github.com/path_to_submodule

You may have deleted your 'projets/fdf' from disk, but your Git repository still has it. Use git rm -rf projets/fdf to remove it from Git, then commit the changes. After that you'll be able to add this folder as a submodule.
