Git：如何只下载一个特定的提交而不克隆存储库的其余部分？

Question

I have a git repository and I want to just download the state of that repository at a particular commit. How do I do that?

I don't intend to make any changes to the repository afterwards, and I don't need the .git folder as I do not want to download unnecessary files. I just want the code in a particular commit.

Is there a way to do that with git?

Answer 1

You can't just download a particular commit. Instead of you can clone a specific branch from the remote repository and then switch to any commit.

Here is the syntax of the command to clone the specific git branch.

git clone -b <BRANCH_NAME> <GIT_REMOTE_URL>

You can use --single-branch to prevent fetching details of other branches like below:

git clone -b <BRANCH_NAME> --single-branch <GIT_REMOTE_URL>

If you go to the directory of your downloaded project and run the following command:

git branch -a

you can see the .git folder does not include information about other branches.

So now, fetch your desired commit by the following command:

git checkout <COMMIT_SHA1_KEY>

Note: You can clone only the latest commit from a given branch by using --depth=n

git clone -b <BRANCH_NAME> --single-branch --depth=2 <GIT_REMOTE_URL>

Answer 2

You can do it with recent enough git and it should be enabled on a server.

Here is how to fetch and checkout commit 71bbabb16755c3d611bb24909e77a0df688827aa as local branch 'main' from https://github.com/curl/curl :

git init curl
cd curl
git fetch --depth=1 https://github.com/curl/curl 71bbabb16755c3d611bb24909e77a0df688827aa:refs/heads/main
git checkout main
