嵌套 git repos 和子模块之间的区别 [英] Difference between nested git repos and submodules

问题描述

git 版本 - 2.6.4

我遇到了无法使用 --recursive 标志克隆完整存储库内容的情况.

I have stuck in a situation where I am not able to clone complete repo content using --recursive flag.

我的主存储库有两个子目录 health-check 和 hellspawn.

My main repository have two sub-directory health-check and hellspawn.

我已经创建了 hellspawn 作为子模块，它也在 .gitmodules 文件中有它的条目.

I have created hellspawn as submodule and it has its entry in .gitmodules file also.

我不确定 health-check 是什么，是 submodule 还是 nested-git.health-check 在 .gitmodules 中没有条目，这让我觉得它可能是 nested-git.

I am not sure what health-check is, whether a submodule or nested-git. health-check does not have entry in .gitmodules which make me thing it might be nested-git.

如果是这样，那么为什么在使用

if so , then why am I getting git message when cloning main repository with

 [e-mail]:~/try$git clone --recursive     
 [e-mail]:url/mainrepo.git 

 Cloning into 'mainrepo'...
 remote: Counting objects: 28713, done.

 No submodule mapping found in .gitmodules for path 'health-check'

`

正如你看到的最后一行，如果 health-check 是嵌套的 git 那么为什么 git 正在检查 .gitmodules 文件??由于这个错误，即使在子模块 hellspawn 中，我也没有下载代码.

As you can see last line if health-check is nested git then why git is checking in .gitmodules file ?? Due to this error, I am not getting code downloaded even in hellspawn which is submodule.

任何帮助

推荐答案

health-check 在 .gitmodules 中没有条目，这让我觉得它可能是嵌套的 git.

health-check does not have entry in .gitmodules which make me thing it might be nested-git.

这是一个嵌套的 git 仓库.

It is a nested git repo.

如果 health-check 是嵌套的 git 那么为什么 git 在 .gitmodules 文件中检查

if health-check is nested git then why git is checking in .gitmodules file

因为嵌套的 git repo 被记录为 gitlink(作为子模块)，这意味着 git 检查 索引中的特殊条目 是否与 .gitmodules 文件(因为git clone 的--recursive 选项，要求克隆子模块)

Because a nested git repo is recorded as a gitlink (as a submodule is), which means git checks if that special entry in the index matches one declared in the .gitmodules file (because of the --recursive option of git clone, asking to clone submodules)

由于该特殊条目与任何 .gitmodules 条目路径不匹配，因此失败并显示警告.

Since that special entry does not match any .gitmodules entry path, it fails with that warning.

由于这个错误，即使在子模块的 hellspawn 中，我也没有下载代码

Due to this error, I am not getting code downloaded even in hellspawn which is submodule

两种方法:

1. 去掉那个特殊的条目:
   尝试 git rm --cached health-check(没有尾随 '/'，正如我在git --recursive 不克隆子模块")，然后添加和推送，然后尝试 git clone --recursive再次

1. Get rid of that special entry:
   Try and git rm --cached health-check (no trailing '/', as I mentioned in "git --recursive doesn't clone submodule"), then add and push, and then try the git clone --recursive again

声明子模块

即:

git config -f .gitmodules submodule.health-check.path health-check
git config -f .gitmodules submodule.health-check.url https://github.com/<auser>/health-check

(用管理该存储库的实际用户替换 )

(replace <auser> by the actual user managing that repo)

再次添加、推送，然后再次尝试 git clone --recursive.

Again, add, push, then try the git clone --recursive again.
