Removing subproject commit from github
提问by Hellboy
I have two repositories namely Aand B. By mistake I cloned repo B inside A on my machine. I removed all the code from the repo B but when I pushed and merged my code from A on origin, it also shows a subproject commit Bon Github repo.
我有两个存储库，即A和B。我错误地在我的机器上的 A 中克隆了 repo B。我从 repo B 中删除了所有代码，但是当我从 A 上推送并合并我的代码时，它还显示了BGithub repo 上的子项目提交。
I want to remove the subproject commit from my master on origin. Will these steps work?
我想从我的 master 上删除子项目提交。这些步骤会奏效吗？
1. rmdir B (on my local repo A)
2. Pushing my repo A to origin
3. Merging

Since GitHub displays B as a gray folder within A repo, that means B has been added to A as a submodule.
That gray folder is a gitlink, a special entry in the index.
由于 GitHub 将 B 显示为 A 存储库中的灰色文件夹，这意味着 B 已作为子模块添加到 A 中。
那个灰色文件夹是一个gitlink，它是索引中的一个特殊条目。
See "How do I remove a Git submodule?":
Locally, do git submodule deinit asubmoduleand git rm B(Bwithout any trailing slash B/).
Then push to GitHub, and Bshould be gone.
请参阅“如何删除 Git 子模块？”：在
本地，执行git submodule deinit asubmodule和git rm B（B没有任何尾部斜杠B/）。
然后push到GitHub，B应该就没了。

转到子模块目录，然后
git checkout <old commit hash>
return back to main project:
返回主项目：
