需要帮助使用现有代码设置新的多项目 Git 本地存储库

Question

I was using Perforce and am switching computers and decided to try Git. I have several projects - source code, electrical engineering files, mechanical engineering files, etc. I would like to keep their commits separate. I also want to be able to tag different commits so that I can get back to a particular configuration (for lack of a better term).

In addition, I want the Git repository to be in a separate folder.

I do not expect to be sharing the code with an online repository or other people. So, I was going to create a local repository and add/commit to it. I'll probably just back this directory to OneDrive or have OneDrive point to the Git repository.

I've read many different blogs and questions but am at a loss on how to proceed and would be very grateful for guidance.

The directory structure is as follows:

c:\Depot c:\Depot\Source c:\Depot\Source\Robot1 c:\Depot\Source\Robot2 c:\Depot\Source\Robot3 c:\Depot\Source\Library c:\Depot\EE c:\Depot\EE\Robot1 c:\Depot\EE\Robot2 c:\Depot\EE\Robot3 c:\Depot\ME c:\Depot\ME\Robot1 c:\Depot\ME\Robot2 c:\Depot\ME\Robot3

Each of the "leaf" directories - ex. Robotx have further sub-directories that I want to track within Robotx .

What I'd like to do is have separate commit histories for each of the Robotx in the Source , EE and ME directories and also for Library . I don't want to use filters to separate them out.

Finally, I want the git repository to be at c:\Depot\Git

I went to c:\Source and did: git init --separate-git-dir Git and that created c:\Source\Git with what seemed like Git files and folders.

To add the first project, I went to c:\Depot\Source and did: git submodule add `pwd`/Robot1 and I got an error message: 'Source/Robot1' already exists and is not a valid git repo

Once you have created a Git repository in a separate folder, you need to set your GIT_DIR environment variable or specify --git-dir in your command line:

git --git-dir=C:\Depot\Git ...

And you can add submodules only if you have already Git repositories for each of your projects.

I would start simple first: simply git init in each of your project, and start adding new commits in your repositories.
Once you have added commits and pushed those projects to a remote location, then you can start testing submodules.
