Hi,

You are missing relative_files = true under your [run] section in .coveragerc. Per the documentation, this is required for Pants to work. Adding this produces the expected output in your HTML report generated by check.py in your repository:

Thanks John, I totally missed the docs for that. Closing this issue.

Hm, I think there's something deeper going on here: Pants attempts to set that property itself, but that is seemingly not working: https://github.com/pantsbuild/pants/blob/e4aaf382459c4362450440b8c20518af446f686c/src/python/pants/backend/python/goals/coverage_py.py#L276-L298

As such, reopening.

I've tried updating the filename of the config from the example above to end with .toml, didn't help
