#19516 isort no longer discovers configuration after 2.14 to 2.16 upgrade Issue created by JordonPhillips Describe the bug A clear and concise description of the bug. I have a python packages with

pyproject.toml

files that contain tool configurations that differ somewhat between each package. Notably

isort

is configured to treat the

tests

directory as a source path. After upgrading to pants 2.16 from 2.14, isort no longer seems to be able to find that

pyproject.toml

as it is not treating the

tests

directory as source. Pants version Which version of Pants are you using? 2.16 OS Are you encountering the bug on MacOS, Linux, or both? MacOS Additional info Add any other information about the problem here, such as attachments or links to gists, if relevant. The BUILD configuration for the tests looks like:

resource(name="pyproject", source="pyproject.toml")

python_test_utils(
    name="test_utils",
    sources=[
        "tests/**/conftest.py",  # pytest's conftest.py file
        "tests/**/*_utils.py",
    ]
)

python_tests(
    name="tests",
    dependencies=[
        ":test_utils",
        ":pyproject",
    ],
    sources=[
        "tests/unit/**/test_*.py",
        "tests/unit/**/tests.py",
        "tests/functional/**/test_*.py",
        "tests/functional/**/tests.py",
        "tests/integration/**/test_*.py",
        "tests/integration/**/tests.py",
    ]
)

There are no files other than

__run.sh

and

pex

in the sandboxes. The pyproject does show up in the

pants dependencies

list though. Also, if I invoke isort directly on the package it does what I would expect. pantsbuild/pants
