如何将已克隆的项目添加为子模块？ [英] How to add already cloned projects as submodules?

问题描述

我在文件夹中有很多我克隆了很长时间的项目;最近我将这个整个文件夹移到我的回购站中，并希望将这些克隆的项目转换为子模块，以便将来能够更好地进行更新和控制。我已经搜索了很多关于如何做到这一点，但所有的教程只讲述如何添加子模块新鲜。任何人都可以帮助我？

解决方案

将现有git存储库添加为子模块与添加新模块相同。

1. 首先将包含所有git存储库的文件夹作为一个git存储库，并使用 git init 。


2. 使用 git submodule add https // example.com / remoterepo ./localrepo ，其中 ./ localrepo 是你现有的git仓库。
   
   
   
   
   • 注意：您从 localrepo / .git获得 remoterepo 的URL / config 。
   
   
   
   • 对您想添加为子模块的所有现有存储库重复第二步。
   
   
   • 现在您可以运行 git submodule foreach git pull 来更新您的所有子项目。
   
   

如果您有很多子模块，您可能需要编写一个小脚本来自动执行第二步，这应该不困难。

编辑

以下是我用于重现评论中提到的错误的内容。我检查了三次命令，并且仍然看不到错误：

  git  - 版本
 
 mkdir子模块测试
 cd子模块测试
 
 git init --bare remote_repo_A 
 git init --bare remote_repo_B 
 
 git clone remote_repo_A local_repo_A 
 git clone remote_repo_B local_repo_B 
 
 cd local_repo_A 
 echotest commit on repo B>> test.txt 
 git add test.txt 
 git commit -m'test commit message'
 git push origin master 
 
 cd ../local_repo_B 
 echo测试提交回购B>> test.txt 
 git add test.txt 
 git commit -m'test commit message'
 git push origin master 
 
 cd ../local_repo_A 
 git clone ../remote_repo_B local_repo_B 
 git submodule add ../remote_repo_B ./local_repo_B 
 git submodule foreach git pull origin master 
 
 git add。 
 git ci -m'我们刚刚为remote_repo_B'
 
添加了一个子模块git子模块状态
  

使用以下命令检查 local_repo_A 的当前状态，它只有两个blob对象，一个用于'test.txt'，另一个用于隐式创建了'.gitmodules'文件， remote_repo_B 都没有添加到 local_repo_A 的索引 。

  find .git / objects -type f | awk -F /'{print $ 3 $ 4}'| xargs -I {} git cat-file -t {} | grep blob 
  

我回滚编辑的原因是因为编辑是简单的错误，它已经<被另外两名调解员和我拒绝了，但后来有一些其他人批准了它，我不确定这是否是SO或错误。但是编辑被拒绝了，即使是现在，因为它完全是错误的，我已经解释了为什么在评论中，我对任何人都没有冒犯性，但是这浪费了我的时间，如果答案对于你再一次，如果你没有改善它，不要编辑我的答案。

I have in a folder a large number of projects that I cloned for quite some time; recently I moved this whole folder into one of my repos and would like to convert these cloned projects into submodules so that I can better update and control in the future. I've googled a lot on how to do this, but all the tutorials only talk about how to add submodules fresh. Anyone can help me?

解决方案

Adding existing git repository as a submodule is the same as adding a new one.

1. First make the folder that contains all your git repositories as itself a git repository with git init.
2. Use git submodule add https//example.com/remoterepo ./localrepo, where ./localrepo is your existing git repository.
   • Note: You get the URL for remoterepo from localrepo/.git/config.
3. Repeat the second step for all your existing repositories that you want to add as submodules.
4. Now you can run git submodule foreach git pull to update all your subprojects.

You may want to write a small script to automate the second step if you have lots of submodules, which shouldn't be difficult.

Edit

The following is what I used for trying to reproduce the error mentioned in the comments. I triple checked the commands, and I still can't see the error:

git --version

mkdir submoduletest
cd submoduletest

git init --bare remote_repo_A
git init --bare remote_repo_B 

git clone remote_repo_A local_repo_A
git clone remote_repo_B local_repo_B

cd local_repo_A
echo "test commit on repo B" >> test.txt
git add test.txt
git commit -m 'test commit message'
git push origin master

cd ../local_repo_B
echo "test commit on repo B" >> test.txt
git add test.txt
git commit -m 'test commit message'
git push origin master

cd ../local_repo_A
git clone ../remote_repo_B local_repo_B
git submodule add ../remote_repo_B ./local_repo_B
git submodule foreach git pull origin master

git add .
git ci -m 'we just added a submodule for remote_repo_B'

git submodule status

Use the following command to check current status of local_repo_A, it has only two blob objects, one for 'test.txt' and another for the implicitly created '.gitmodules' file, nothing from remote_repo_B are added to the index of local_repo_A.

find .git/objects -type f | awk -F/ '{print $3$4}' | xargs -I {} git cat-file -t {} | grep blob

The reason I rolled back the edits is because the edits is simply WRONG, it was already rejected by two other mediators and me, but later some other guy approved it, I am not sure if it is a bug of SO or what. But the edits are rejected, even now because it's totally wrong, I already explained why in the comments, I am no offensive to anyone, but this wasted my time, downvote it if the answer is not helpful to you.

Again, if you are not improving it, DON'T edit my answer.
