Hi! Is it possible to exclude some directory from containing source roots? We have a

third-party

folder which contains forks of other repositories, which we would like to exclude from the source roots. The following does not work:

[source]
root_patterns = ["/", "src", "src/python", "tests", "!/third-party"]

Take a look at https://www.pantsbuild.org/dev/reference/global-options#pants_ignore

Thanks, but I would like to have pants see these files, e.g. for targets that build wheels of those dependencies. Just not use them as source roots

What is the issue with actually having them be source roots?

I ran into the issue that one of these packages has a "datasets" module in the source, root which conflicted with a PyPI package by that name. I know that with pants, I can normally explicitly choose a dependency, but here I used

pants roots

to setup my development environment (as recommended in the docs) and that made the that package in the monorepo shadow the PyPI package

How many true source roots do you have? Is it tractable to mark them with

marker_filenames

instead of matching them to patterns?

Thanks for the suggestion. A few dozen. Would be mildly annoying to have to move to markers, but tolerable.

The marker could potentially be a file you already have in every source root (like a pyproject.toml or similar)
