How to “git clone” including submodules?

Question

I\'m trying to put a submodule into a repo. The problem is that when I clone the parent repo, the submodule folder is entirely empty.

Is there any way to make it so

Answer 1

Submodules parallel fetch aims at reducing the time required to fetch a repositories and all of its related submodules by enabling the fetching of multiple repositories at once. This can be accomplished by using the new --jobs option, e.g.:

git fetch --recurse-submodules --jobs=4

According to Git team, this can substantially speed up updating repositories that contain many submodules. When using --recurse-submodules without the new --jobs option, Git will fetch submodules one by one.
