假设我有一个带有子模块 A 的存储库 X。现在假设我希望 X 有两个分支：master 和development。我希望 master 拥有与开发版本不同的 A 版本。如何在这些分支之间来回切换？
我已经设置了一个存储库来执行此操作（但使用真实姓名而不是假名！）。问题是，每当我从开发中执行 git checkout master 时，我都会得到以下信息：
$ git co master
M A
Switched to branch 'master'
看起来它没有将 A 返回到 master 引用的提交。有什么办法解决这个问题吗？ git submodulesync 和 git submodule update 似乎都没有改变任何东西。
Suppose I have a repository X with a sub module A. Now suppose I want X to have two branches: master and development. I want master to have a different revision of A than development does. How can I switch back and forth between these branches?
I've got a repository set up that does this (but using real names instead of fake ones!). The problem is that whenever I do git checkout master from development, I get the following:
$ git co master
M A
Switched to branch 'master'
It looks like it's not putting A back to the commit that master references. Is there any way around this? Both git submodule sync and git submodule update don't seem to change anything.
