I'm working on a project in one git repository (A) that is including another git repository (B), which in turn includes a third git repository (C). In A, I added B via:
git submodule add https://github.com/blt04/sfDoctrine2Plugin.git plugins/sfDoctrine2Plugin Click here, and you can see where B references C: https://github.com/doctrine/doctrine2
After doing my git submodule add, my plugins/sfDoctrine2Plugin/lib/vendor/doctrine folder (should contain C) is empty. I tried doing a git submodule update --recursive as per this StackOverflow answer, but it still didn't import the files to that path. I'm at a loss as to what to do here.

If you pass --recurse-submodules to the git clone command, it will automatically initialize and update each submodule in the repository, including nested submodules if any of the submodules in the repository have submodules themselves.
Git allows you to include other Git repositories called submodules into a repository. This allows you to track changes in several repositories via a central one. Submodules are Git repositories nested inside a parent Git repository at a specific path in the parent repository's working directory.
git submodule sync synchronizes all submodules while git submodule sync -- A synchronizes submodule "A" only. If --recursive is specified, this command will recurse into the registered submodules, and sync any nested submodules within.
The list of steps required to clone a Git repository with submodules is: Issue a git clone command on the parent repository. Issue a git submodule init command. Issue a git submodule update command.
You need to do git submodule update --init --recursive. The problem here is the submodule C is never being initialized in the first place.
