当您已有本地副本时，如何初始化git子模块？

Question

I already have a git repo inside another one. Let's say the directory structure is:

repo1
  --.git
  --repo2
    --.git

How would I be able to tell git I want repo2 to be a submodule? Note that I already have the entire git repo on disk (I tried doing git submodule add repo2 , but it said repo URL: 'repo2' must be absolute or begin with ./|../ )

Answer 1

I believe what you want is git submodule add <URL> repo2 . Essentially, you always want a remote URL to point to (think about how you initialize a git repo: git clone <repo> . Hence, it shouldn't be different for git submodules
