            Failure Info:

            This job uses the semver from the git TAG as the public version to publish.

            - This should only run on workflows triggered by a tag.
            - The tag name should be a semver like 'v1.2.3'
            - The version should follow conventions documented at https://github.com/fsaintjacques/semver-tool
