New warning from conda-forge linting-process / souschef

[willend]

Hi there,

I have a couple of conda-forge feedstocks (mcstas-suite,mcxtrace-suite) that build multiple packages through a single feedstock-recipe, and were we use "non-standard" naming of the buildscripts for Unix and Windows, namely e.g.

outputs:

  - name: mcstas-core
    script: install-files-core.sh  # [unix]
    script: install-files-core.bat  # [win]

I noticed that conda-souschef (in fact maybe a new YaML release?) recently has started complaining / warning about this:

2024-11-26 08:24:37,400 WARNING conda_smithy.linter.lints || Error parsing recipe with conda-souschef: DuplicateKeyError('while constructing a mapping', in "<unicode string>", line 19, column 5:

After a discussion on Zulip I was asked to file an issue here.
