More easily resolve which version has missing attributes
When Antora's playbook is configured with a multi-branch / multi-tag configuration, when Asciidoc skips an attribute because it cannot be resolved, its difficult to determine which version the warning is be emitted from?
Given this playbook configuration:
content:
sources:
- url: /project
start_path: documentation
branches:
- '1.0'
- '1.1'
- '1.2'
- '2.0'
- '2.1'
tags:
- 'v1.1.1.RELEASE'
- 'v1.1.2.RELEASE'
This is an example of the output:
asciidoctor: WARNING: skipping reference to missing attribute: attributea
asciidoctor: WARNING: skipping reference to missing attribute: attributeb
asciidoctor: WARNING: skipping reference to missing attribute: attributeb
asciidoctor: WARNING: skipping reference to missing attribute: attributeb
asciidoctor: WARNING: skipping reference to missing attribute: attributea
Would it be possible to emit a message or something with the warning that indicates which branch/tag the warning originates?
