We've started receiving messages like this during codegen: ``` /tmp/build-env-w9fmceq7/lib/python3.12/site-packages/setuptools/dist.py:759: SetuptoolsDeprecationWarning: License classifiers are deprecated. !! ******************************************************************************** Please consider removing the following classifiers in favor of a SPDX license expression: License :: OSI Approved :: MIT License See https://packaging.python.org/en/latest/guides/writing-pyproject-toml/#license for details. ******************************************************************************** !! self._finalize_license_expression() ``` This is telling us to stop specifying "License :: OSI Approved :: MIT License" in the setup.py classifiers in favor of this SPDX format ... in a pyproject.toml, which we don't have. --- The pyproject.toml format wants us to specify something like ``` [project] license = "MIT" license-files = ["LICENSE", "NILICENSE"] ``` Maybe we would need to AND with another license in the "license" field for the "NI General Purpose EULA" that's covered in the NILICENSE file. This may be a bigger discussion that we need to have internally. ---- Before we can do that, though, we'll first need to add a pyproject.toml. See https://packaging.python.org/en/latest/guides/modernize-setup-py-project/#modernize-setup-py-project Although pyproject.toml is not required yet, it's strongly recommended.
