Today I learned how to git clone a repository that has git submodules inside of it. I realized that when I cloned a project it will clone the parent repo but the submodules will be empty. Here are the steps on how to clone it properly.
If you haven’t cloned the repository yet, you can use
1$ git clone --recurse-submodules https://github.com/sample/sample-repo.git
Otherwise, If you already cloned the project then you can use the following command. Run the command inside your git repository.
1$ git submodule update --init --recursive
This will initialize, fetch and checkout any nested submodules for the repository. That’s it.
