Hi! This is the friendly automated conda-forge-linting service.

I just wanted to let you know that I linted all conda-recipes in your PR (recipe/meta.yaml) and found it was in an excellent condition.
I do have some suggestions for making it better though...

For recipe/meta.yaml:

• License is not an SPDX identifier (or a custom LicenseRef) nor an SPDX license expression.

Documentation on acceptable licenses can be found here.

@Tieqiong please check, I think we may need to change the python versions in the meta.yaml.

@sbillinge For some reason the Azure pipeline check was not run, and I believe it's also happening for diffpy.utils. We might not be able to release to conda-forge before figuring this out...

[sbillinge]

Ah, o missed that in this case. Yes, let's not merge any more until we sort this out

[bobleesj]

@Tieqiong @sbillinge Just wanted to share our merged CI failed, hence 3.3.0 isn't available on conda-forge: https://anaconda.org/conda-forge/diffpy.structure/files

[Tieqiong]

@bobleesj where were you able to see the checks?

[bobleesj]

in the main repo

[Tieqiong]

@bobleesj It seems like nothing was actually run. they all stop at very early stage in a few seconds. Were you able to run Azure pipeline in other feedstocks PRs?

[bobleesj]

Oddly, yes https://github.com/conda-forge/diffpy.labpdfproc-feedstock - it does not have the permission problem like here.

In diffpy.utils-feedstock, I've tagged admins for help.

@Tieqiong CI running again - git commit --allow-empty -m "push empty, re-run CI" worked
