How to download a specific commit from a Git repository

[rogerxu]

Sometimes we need to download a specific version of a project from a Git repository to do some work like build from source code. If clone the entire repository it will be very slow because we don't need the entire commit history.

GitHub provides a download as zip service for a specific version which meets our needs. But how about a Git repository accessed via SSH?

Excluding files from git archive exports using gitattributes

Git - git-archive Documentation

git archive [--format=<fmt>] [--list] [--prefix=<prefix>/] [<extra>]
          [-o <file> | --output=<file>] [--worktree-attributes]
          [--remote=<repo> [--exec=<git-upload-archive>]] <tree-ish>
          [<path>…​]

Example:

git archive -v --format=zip --output=archive.zip [email protected]:rogerxu/webpack-demo.git master app/images

Download URL

You can put the sha that you want in the download url:

https://github.com/{username}/{projectname}/archive/{sha}.zip

As a general rule, if you have a url that works, you can replace "master" with the specific sha you want.

git archive --remote

As far as I know Github does not allow archive --remote for HTTPS protocol. git archive works fine with GitHub, as long as you use the ssh protocol.

git archive -v --format=zip --output=archive.zip [email protected]:rogerxu/webpack-demo.git master app/images

svn export
