我发现从子模块获取本地提交数据更方便，否则我就会丢失它们。(无法推送，因为我没有遥控器)。所以我添加了submodule/。Git为remote_origin2，从该分支中提交并合并。 不确定我是否仍然需要子模块远程作为起源，因为我对git还不够熟悉。

当

git rm [-r] --cached submodule_path

返回

fatal: pathspec 'emr/normalizers/' did not match any files

背景:我在子模块文件夹中执行了rm -r .git*，然后才意识到它们需要在我刚刚添加它们的主项目中去子模块化。我得到了上面的错误去子模化一些，但不是所有的。不管怎样，我通过运行(当然，在rm -r .git*之后)来修复它们。

mv submodule_path submodule_path.temp
git add -A .
git commit -m "De-submodulization phase 1/2"
mv submodule_path.temp submodule_path
git add -A .
git commit -m "De-submodulization phase 2/2"

注意，这并不能保存历史。

我找到的最佳答案是:

http://x3ro.de/2013/09/01/Integrating-a-submodule-into-the-parent-repository.html

这篇文章很好地解释了这个过程。

以下是我发现的最好最简单的方法。

在子模块repo中，你想从HEAD合并到main repo:

git checkout -b "mergeMe" mkdir "foo/bar/myLib/"(与你想要在主repo上的文件的路径相同) git mv * "foo/bar/myLib/"(移动所有到路径) Git commit -m“准备合并到main”

在删除子模块并清除路径"foo/bar/myLib"后，回到主repo:

SubmoduleOriginRemote/mergeMe

繁荣做

记录保存

不用担心

注意，这与其他一些答案几乎相同。但这假设你拥有子模块repo。此外，这也使子模块的未来上游更改变得容易。

我已经创建了一个脚本，将子模块转换到一个简单的目录，同时保留所有的文件历史。它不会像其他解决方案那样受到git log——follow <file>问题的困扰。它也是一个非常简单的单行调用，可以为您完成所有工作。G 'luck。

它建立在Lucas Jenß的出色工作之上，在他的博客文章“将子模块集成到父存储库中”中描述了这一点，但是它自动化了整个过程，并清理了一些其他的极端情况。

最新的代码将在github上的https://github.com/jeremysears/scripts/blob/master/bin/git-submodule-rewrite上进行错误修复，但为了适当的stackoverflow回答协议，我在下面包含了完整的解决方案。

用法:

$ git-submodule-rewrite <submodule-name>

git-submodule-rewrite:

#!/usr/bin/env bash

# This script builds on the excellent work by Lucas Jenß, described in his blog
# post "Integrating a submodule into the parent repository", but automates the
# entire process and cleans up a few other corner cases.

    This script will convert your "${sub}" git submodule into
    a simple subdirectory in the parent repository while retaining all
    contents and file history.

    The script will:
      * delete the ${sub} submodule configuration from .gitmodules and
        .git/config and commit it.
      * rewrite the entire history of the ${sub} submodule so that all
        paths are prefixed by ${path}.
        This ensures that git log will correctly follow the original file
        history.
      * merge the submodule into its parent repository and commit it.

    NOTE: This script might completely garble your repository, so PLEASE apply
    this only to a fresh clone of the repository where it does not matter if
    the repo is destroyed.  It would be wise to keep a backup clone of your
    repository, so that you can reconstitute it if need be.  You have been
    warned.  Use at your own risk.

main

这里有很多答案，但它们似乎都过于复杂，可能不能达到你想要的效果。我相信大多数人都想保留他们的历史。

在这个例子中，主repo将是git@site.com:main/main.git，子模块repo将是git@site.com:main/child.git。这假设子模块位于父repo的根目录中。根据需要调整说明书。

首先克隆父repo并删除旧的子模块。

git clone git@site.com:main/main.git
git submodule deinit child
git rm child
git add --all
git commit -m "remove child submodule"

现在我们将把子回购添加到主回购的上游。

git remote add upstream git@site.com:main/child.git
git fetch upstream
git checkout -b merge-prep upstream/master

下一步假设您希望将merge-prep分支上的文件移动到与上面的子模块相同的位置，尽管您可以通过更改文件路径轻松更改位置。

mkdir child

将除.git文件夹外的所有文件夹和文件移动到子文件夹中。

git add --all
git commit -m "merge prep"

现在您可以简单地将文件合并回主分支。

git checkout master
git merge merge-prep # --allow-unrelated-histories merge-prep flag may be required 

在运行git push之前，环顾四周，确保一切看起来都很好

你现在必须记住的一件事是，git日志默认情况下不会跟踪移动的文件，但是通过运行git log——follow filename，你可以看到你文件的完整历史。
