How to use git + gitea to work with a project from self-contained sub-projects?

Question

git

Good day.

I use : git, gitea (no internet), vscode.

I have the following project structure:

Project Structure

Зеленый прямоугольник - файл входит в состав большого проекта и в состав подпроекта.
Желтый прямоугольник - файл входит только в состав подпроекта.

Is it possible with the help of the programs I use to implement the project scheme I have given? Each subproject is developed by one developer, the subproject includes files that are not needed for the main project.

Answer 1

Better do it like this

- Common
    |-- file1
    |-- file2
    |-- fileX
-Project1
    |-- file1
    |-- file2
    |-- fileX
-Project2
    |-- file1
    |-- file2
    |-- fileX
