如何使用git子模块检查子模块的特定版本？ [英] How to check out specific version of a submodule using git submodule?

问题描述

子模块存储库保持分离HEAD状态指向特定的提交。更改该提交只需检出一个不同的标记或提交，然后将更改添加到父存储库。

  $ cd submodule 
 $ git checkout v2.0 
以前的HEAD位置是5c1277e ...碰撞版本为2.0.5 
 HEAD现在在f0a0036 ...版本2.0 
  

git-status 现在会报告一个脏树：

 ＃分支开发[...] 
＃
＃修改：子模块（新提交）
  

添加子模块目录并提交以存储新指针。

How would I go about adding a git submodule for a specific tag or commit?

解决方案

Submodule repositories stay in a detached HEAD state pointing to a specific commit. Changing that commit simply involves checking out a different tag or commit then adding the change to the parent repository.

$ cd submodule
$ git checkout v2.0
Previous HEAD position was 5c1277e... bumped version to 2.0.5
HEAD is now at f0a0036... version 2.0

git-status on the parent repository will now report a dirty tree:

# On branch dev [...]
#
#   modified:   submodule (new commits)

Add the submodule directory and commit to store the new pointer.
