Git Pull with Submodule

原文链接

If it's the first time you checkout a repo you need to use --init first:

git submodule update --init --recursive

For git 1.8.2 or above the option --remote was added to support updating to latest tips of remote branches:

git submodule update --recursive --remote

This has the added benefit of respecting any "non default" branches specified in the .gitmodules or .git/config files (if you happen to have any, default is origin/master, in which case some of the other answers here would work as well).

For git 1.7.3 or above you can use (but the below gotchas around what update does still apply):

git submodule update --recursive

or:

git pull --recurse-submodules

if you want to pull your submodules to latest commits intead of what the repo points to.

See git-submodule(1) for details

OR

Git Pull with Submodule

For a repo with submodules, we can pull all submodules using

git submodule update --init --recursive

for the first time. All submodules will be pulled down locally.

To update submodules, we can use

git submodule update --recursive --remote

or simply

git pull --recurse-submodules

The first one works for git version 1.8.2 or above while the second one works for git version 1.7.3 or above.
