是否可以仅对 git repo 的子目录中的文件进行稀疏结帐？

Question

I want to deploy the contents of a React's build folder to tomcat's webapps directory.

The project on Github is called dashboard and it has a sub-directory called client which holds the development code as well as the production build file (/client/build). I want to pull the contents of that build file into a directory called dashboard/ in webapps/.

I've tried using sparse-checkout but what happens is the full path (/client/build) is placed in the dashboard directory. So instead of webapps/dashboard/ contents of build folder the structure is webapps/dashboard/client/build/ contents of build folder .

Is there a way to only extract the files from a folder with sparse-checkout or is there a way to configure tomcat to look into /client/build for the files it needs?

Answer 1

You can use sparse checkout mode to check out a limited subset of files, but you cannot use this to rename the files. If the file's name is a/b/c/d —note that file names don't contain folder names; a/b/c/d is just a file name; it is your OS, not Git, that insists on storing this as a file d within a folder c and so on—then as far as Git is concerned, that file's name is a/b/c/d . ¹ The sparse checkout code will check it out using that name.

What you can do quite easily is use git archive to produce a tarball or zip archive, then use any un-archiver that allows you to skip some number of pathname components; or, if you have just a single file to extract, use git show or git cat-file -p to extract the file, and direct the output of this command to a file.

¹ I'm thinking about a general method of handling file renaming issues, but it's still in formative stages, and there's no guarantee that the Git project folks will buy into anything I come up with here.
