背景

在Linux上使用Git 1.8.1.1.存储库如下所示:

master
  book

子模块创建如下:

$ cd /path/to/master
$ git submodule add https://user@bitbucket.org/user/repo.git book

该book子模块是干净的:

$ cd /path/to/master/book/
$ git status
# On branch master
nothing to commit, working directory clean

问题

另一方面,主人显示书子模块有"新提交":

$ cd /path/to/master/
$ git status
# On branch master
# Changes not staged for commit:
#   (use "git add <file>..." to update what will be committed)
#   (use "git checkout -- <file>..." to discard changes in working directory)
#
#       modified:   book (new …

我正在尝试使用git子模块将10多个存储库聚合到一个结构中以便于开发.

它应该克隆模块并签出分支.而是以分离头模式检出模块.

git clone git@github.com:org/global-repository.git
git submodule update —init
cd config-framework
git status

$git status
#HEAD detached at b932ab5
nothing to commit, working directory clean

gitmodules文件似乎没问题

$cat .gitmodules 
[submodule "config-framework"]
        path = config-framework
        url = git@github.com:org/config-framework.git
        branch = MY_BRANCH

我们希望默认情况下检出MY_BRANCH分支,而不是分离头.我们如何实现这一目标？
