How to use someone else's repository in your own?

Question

git

I have my repository (A) and I clone another user's repository (B) into my repo. And if I want to change repository B, then git swears and does not allow me to do this. Colonized with (git clone)

Answer 1

There are 3 options:
1. Add a third-party repository as a submodule:
git submodule add B_repo_url
This method is suitable if you do not want to store third-party code in your repository or split your repository into several different repositories (modules).
When cloning to another machine, you will need to add the --recursive flag to the "git clone" command to clone all code, including submodules.
git clone repo_A_url --recursive
or

git clone repo_A_url && git submodule update --init

2. Copy the code of a third-party repository to your repository (partially or completely) and place it in a subfolder of yours, for example, external/B
This option is suitable if the third-party repository is not available via Git or you are calmer when all the code is in your repository, and not where -something there.
3. Add as a "subtree" via git-subtree
git-subtree is something between the first two - the code will be copied into your repository from a third party repository, but you can automatically pull changes to a third party repository via git subtree pull, just like with submodules (i.e. you don't have to manually copy the code with a new release).
