注意:Git 1.8.2增加了跟踪分支的可能性。下面是一些答案。

习惯这一点有点令人困惑，但子模块并不在分支上。正如您所说，它们只是指向子模块存储库的特定提交的指针。

这意味着，当其他人签出你的存储库，或提取你的代码，并进行git子模块更新时，子模块将被签出到特定的提交。

这对于不经常更改的子模块非常有用，因为这样项目中的每个人都可以在同一次提交时拥有子模块。

如果你想移动子模块到一个特定的标签:

cd submodule_directory
git checkout v1.0
cd ..
git add submodule_directory
git commit -m "moved submodule to v1.0"
git push

然后，另一个希望将submodule_directory更改为该标记的开发人员执行此操作

git pull
git submodule update --init

Git拉修改提交他们的子模块目录指向。Git子模块update实际上合并到新代码中。

根据我的经验，在超级项目或未来的签出中切换分支仍然会导致子模块的头部分离，无论子模块是否正确添加和跟踪(即@djacobs7和@Johnny Z答案)。

而不是手动签出正确的分支手动或通过脚本git子模块foreach可以使用。

这将检查子模块配置文件中的分支属性并检出set分支。

Git子模块foreach -q——recursive 'branch="$(Git config -f $ topllevel . "gitmodules子模块。name.branch美元)”;Git checkout $branch'

Git 1.8.2增加了跟踪分支的可能性。

# add submodule to track branch_name branch
git submodule add -b branch_name URL_to_Git_repo optional_directory_rename

# update your submodule
git submodule update --remote 

参见Git子模块

为了切换子模块的分支(假设你已经将子模块作为存储库的一部分):

CD到包含子模块的存储库的根目录 打开.gitmodules进行编辑 在path =…url =…对于每个子模块，它说branch = your-branch;保存文件。gitmodules。 然后在不改变目录的情况下执行$ git子模块update——remote

.．.对于这样修改的每个子模块，这应该拉入指定分支上的最新提交。
