How to create a repo whose code are used by two other projects?

I currently have two separate repositories, say A and B for building two products. There are a large number of common code exist in both repositories. I want to create a repo C to host those common code and remove them from both A and B. My question is: how to clone, checkout, commit either one of the product code together with the common code, i.e., (A, C) or (B, C) consistently? Can it be done in SourceTree?

There are two options, three is you want to use git submodules which I do not recommend. You can either use Git subtrees to do it, or repo which is a tool from Google. Git subtrees works best for Bitbucket/Sourcetree. You can find out more about Git subtrees in this article, Alternatives To Git Submodule: Git Subtree
