9.2.0 ignores [tool.setuptools_scm] with metadata in setup.cfg #1213
Description
We have a suite of python projects being deployed on RHEL9 which require keeping package metadata in setup.cfg in order to build RPM packages in the RHEL environment. All of these packages are using setuptools-scm configuration with a version file and a non-default version_scheme.
Starting with 9.2.0 all these packages are failing trying to import version data from the missing version file, with the following warning message when building:
$ SETUPTOOLS_SCM_DEBUG=1 python -m build .
