Submodule

Submodule can be useful when a project is dependent on another isolated project on build. Such as a project your team is working on but maintained separately, or third party dependencies that are not available from any package manager.

Add Submodule

git submodule add <repository_url> <path_to_submodule>

Details of submodules can be inspected from .gitmodules

Clone with Submodule

Fetching submodule on clone:

git clone <url> --recursive

If you forgot to append --recursive option when cloning for the first time, you can still remedy using the following command.

git submodule update --init --recursive
