Actually, git-stitch-repo now supports branches and tags, including annotated tags (I found there was a bug which I reported, and it got fixed). What i found useful is with tags. Since tags are attached to commits, and some of the solutions (like Eric Lee's approach) fails to deal with tags. You try to create a branch off an imported tag, and it will undo any git merges/moves and sends you back like the consolidated repository being near identical to the repository that the tag came from. Also, there are issues if you use the same tag across multiple repositories that you 'merged/consolidated'. For example, if you have repo's A ad B, both having tag rel_1.0. You merge repo A and repo B into repo AB. Since rel_1.0 tags are on two different commits (one for A and one for B), which tag will be visible in AB? Either the tag from the imported repo A or from imported repo B, but not both.

git-stitch-repo helps to address that problem by creating rel_1.0-A and rel_1.0-B tags. You may not be able to checkout rel_1.0 tag and expect both, but at least you can see both, and theoretically, you can merge them into a common local branch then create a rel_1.0 tag on that merged branch (assuming you just merge and not change source code). It's better to work with branches, as you can merge like branches from each repo into local branches. (dev-a and dev-b can be merged into a local dev branch which can then be pushed to origin).

也许，简单地(类似于前面的答案，但使用更简单的命令)在每个单独的旧存储库中进行提交，将内容移动到一个适当命名的子目录中，例如:

$ cd phd/code
$ mkdir code
# This won't work literally, because * would also match the new code/ subdir, but you understand what I mean:
$ git mv * code/
$ git commit -m "preparing the code directory for migration"

然后将三个单独的回购合并为一个新的，通过这样做SMTH:

$ cd ../..
$ mkdir phd.all
$ cd phd.all
$ git init
$ git pull ../phd/code
...

然后您将保存历史记录，但将继续进行单个回购。

我创造了一个工具来完成这项任务。使用的方法是类似的(内部做一些东西，如——filter-branch)，但更友好。是GPL 2.0

我把解也写在这里。它基本上是一个围绕git过滤器分支的相当简单的bash脚本包装器。像其他解决方案一样，它只迁移主分支，而不迁移标签。但是完整的主提交历史被迁移了，它是一个简短的bash脚本，因此用户应该相对容易检查或调整。

下面是我给出的一个解决方案:

First do a complete backup of your phd directory: I don't want to be held responsible for your losing years of hard work! ;-) $ cp -r phd phd-backup Move the content of phd/code to phd/code/code, and fix the history so that it looks like it has always been there (this uses git's filter-branch command): $ cd phd/code $ git filter-branch --index-filter \ 'git ls-files -s | sed "s#\t#&code/#" | GIT_INDEX_FILE=$GIT_INDEX_FILE.new \ git update-index --index-info && mv $GIT_INDEX_FILE.new $GIT_INDEX_FILE' HEAD Same for the content of phd/figures and phd/thesis (just replace code with figures and thesis).

现在你的目录结构应该是这样的:

    phd
      |_code
      |    |_.git
      |    |_code
      |         |_(your code...)
      |_figures
      |    |_.git
      |    |_figures
      |         |_(your figures...)
      |_thesis
           |_.git
           |_thesis
                |_(your thesis...)

然后在根目录中创建一个git存储库，将所有内容都拉到其中，并删除旧的存储库: $ CD博士 $ git init $ git拉码 $ rm -rf code/code $ rm -rf代码/.git $ git拉数据-允许不相关的历史 $ rm -rf figures/数字 $ rm -rf数字/.git $ git拉论文-允许不相关的历史 $ rm -rf thesis/thesis $ rm -rf thesis/.git

最后，你现在应该得到你想要的:

    phd
      |_.git
      |_code
      |    |_(your code...)
      |_figures
      |    |_(your figures...)
      |_thesis
           |_(your thesis...)

这个过程的一个优点是，它将保留不受版本控制的文件和目录。

不过，只有一个警告:如果您的代码目录已经有一个代码子目录或文件，情况可能会非常糟糕(当然，对于图表和论文也是如此)。如果是这种情况，在执行整个过程之前，只需重命名该目录或文件:

$ cd phd/code
$ git mv code code-repository-migration
$ git commit -m "preparing the code directory for migration"

当程序完成后，添加最后一步:

$ cd phd
$ git mv code/code-repository-migration code/code
$ git commit -m "final step for code directory migration"

当然，如果代码子目录或文件没有版本控制，只需使用mv而不是git mv，忘记git的提交。

@MiniQuark解决方案帮助了我很多，但不幸的是，它没有考虑到源存储库中的标记(至少在我的情况下)。以下是我对@ mini夸克答案的改进。

First create directory which will contain composed repo and merged repos, create directory for each merged one. $ mkdir new_phd $ mkdir new_phd/code $ mkdir new_phd/figures $ mkdir new_phd/thesis Do a pull of each repository and fetch all tags. (Presenting instructions only for code sub-directory) $ cd new_phd/code $ git init $ git pull ../../original_phd/code master $ git fetch ../../original_phd/code refs/tags/*:refs/tags/* (This is improvement to point 2 in MiniQuark answer) Move the content of new_phd/code to new_phd/code/code and add code_ prefeix before each tag $ git filter-branch --index-filter 'git ls-files -s | sed "s-\t\"*-&code/-" | GIT_INDEX_FILE=$GIT_INDEX_FILE.new git update-index --index-info && mv $GIT_INDEX_FILE.new $GIT_INDEX_FILE' --tag-name-filter 'sed "s-.*-code_&-"' HEAD After doing so there will be twice as many tags as it was before doing filter-branch. Old tags remain in repo and new tags with code_ prefix are added. $ git tag mytag1 code_mytag1 Remove old tags manually: $ ls .git/refs/tags/* | grep -v "/code_" | xargs rm Repeat point 2,3,4 for other subdirectories Now we have structure of directories as in @MiniQuark anwser point 3. Do as in point 4 of MiniQuark anwser, but after doing a pull and before removing .git dir, fetch tags: $ git fetch catalog refs/tags/*:refs/tags/* Continue..

这是另一个解。希望它能帮助别人，它帮助了我:)
