Git ignore the deletion of a tracked file

Question

scenario

I've a folder /build that is regenerated at each build process. This folder needs to be versioned and the content must be excluded, so in the .gitignore I've added build/* and a /build/.gitkeep to be able to add the folder.

problem

When the content is generated it deletes the .gitkeep file that was previously tracked by git. I would like to know if there is any way to ignore the deletion of this file. I'm looking for a solution that can works across repos, since git update-index --assume-unchanged <file> only seems to work locally and would need to be executed on each clone.

如果将它添加到回购中的检出后挂钩中，则可以在每个客户端上自动运行假定不变的命令。

Answer 2

This sounds more like something you could achieve with your build tool. What are you using to build? could you look into making a script that writes the .gitkeep file to the build/ folder after a build operation has been executed?

The script would be very simple, along the lines of (in a unix system):

#!/bin/sh
touch build/.gitkeep
