[Feature Reqeust] Mirror all submodules recursively

[duanshiqiang]

Currently this program doesn't mirror any submodule which sometimes is the largest compared with the main repo.

Supporting mirror all submodules would be nice.

Yeah, I remember thinking about adding this. But, the last time I checked (which was probably 2015), the Git plugin for Jenkins did not use the reference repo for submodules. So while I agree mirroring submodules would be a useful addition to this software, I'm not sure Jenkins would actually use it.

Also, I'm not really maintaining this software any more, so it's not very likely that I will implement this…
