`build.rs` line change slows tests

The following line in my build.rs makes nextest take 100s+ instead of 12s:

    println!("cargo::rerun-if-changed=.git/HEAD");

This is on rust 1.77. When I was on 1.74, the line looked like this, and didn't have an effect on test speed:

    println!("cargo:rustc-rerun-if-changed=.git/HEAD");

If I remove the line, tests are fast again. Worth noting that cargo test --all is not affected by this.

Thanks for the report! That sounds like a build-time thing which nextest doesn't customize in any way. Do you have a minimal repro or example somewhere?

I'm not experiencing this anymore and I forgot how I resolved it, sorry! Closing.
