Git history is overriden by the build process

[Thomasorus]

Behaviour

I built a static site generator in python and use the git commit history of markdown files to display a "Last modified" date on the built website. When used locally, my build process works and display the date correctly.

But when I used this github action, the git history seems to disappear entirely and the date displayed is the built date,

Demo files

1. You can see that this file last modification is may 24.
2. But the built page shows May 29, the last time the site was built.

Expected behaviour

The date on the built page should be may 24.

Actual behaviour

The date on the built page is May 29,

Thanks for your help.

This is the intended behavior of your configuration. You set keep_history: false.

Even if keep_history is set to true, this action would create a commit having the build date as date (and not some other date).

I'm gonna try this, thanks!
