I need o duplicate one folder in my project o another. But when I try:
git submodule add ./first-folder ./second-folder/sumbodule
it fails with:
fatal: clone of '[email protected]:username/projectname.git/first-folder' into submodule path
Am I doing something wrong or it's impossible by default and I should just mount it somehow? Thanks.
You can only add entire repositories as submodules. See git submodule documentation. There is a parameter path but that applies to the path where the submodule appears in the 'superproject', not to a path inside the submodule.
To achieve what you want, you need to make the first-folder a separate git repository and include that as submodule to all of your projects.
From ./second-folder/sumbodule, try to execute below command:
cd ./second-folder
git submodule add <git@github ...> sumbodule
This is now possible with sparse-checkout and symbolic links. For more details on how this works, please check out this gist

The general idea is that you first add the submodule, then set up sparse-checkout in the submodule to track only the folders or files you need. Then you could use symbolic links to "place" the folder wherever you want.
