Current evaluation

Maintainer-filed, triaged enhancement to honour the disable-parallel part property in the jlink plugin. Labeled Needs information; jlink never uses parallel_build_count, so the property would likely be a no-op. Open 395 days, no comments.

Suggested action: keep open

Reason: The issue is valid and already categorised (labels 'Type: Enhancement' and 'Status: Needs information', filed by maintainer lengau), so it is triaged rather than needing triage. Code inspection shows the ask is essentially inert here: unlike the make/cmake/ant/go/maven plugins, `craft_parts/plugins/jlink_plugin.py` never references `self._part_info.parallel_build_count`, so adding `disable_parallel` would change no emitted command — hence impact is minimal and the maintainer's own note that it is "extremely low priority until someone shows us a real-world use case" is still unaddressed with 0 comments. Age alone is not a reason to close, and the jlink plugin is an active, current component, so keep it open pending a use case.

Issue body

### What needs to get done Support the [disable-parallel](https://canonical-craft-parts.readthedocs-hosted.com/latest/common/craft-parts/reference/part_properties/#disable-parallel) part property in the jlink plugin. ### Why it needs to get done All of our plugins should theoretically support this. In practice though, this is extremely low priority until someone shows us a real-world use case for it. If someone can bring us a real-world use case that we can test against (especially a case of "this application simply does not build with parallel"), that would be ideal. The [autotools plugin](https://github.com/canonical/craft-parts/pull/1167) required this for OpenJDK builds, for example.

  • Related To: canonical/craft-parts#1242 (confidence 95%)

    Same 'plugin: Support disable-parallel parameter' family; the make plugin does emit -j${parallel_build_count}, so it is a more meaningful instance of the same request.

  • Related To: canonical/craft-parts#1234 (confidence 93%)

    cmake plugin sibling issue, also emits -j${parallel_build_count} and is labelled Needs information.

  • Related To: canonical/craft-parts#1167 (confidence 90%)

    PR cited in the issue body: commit 7dfd1bf7 'feat: add parallel parameter to autotools plugin' is the reference implementation (autotools_plugin.py:49,133) and the changelog template for this feature.

  • Related To: canonical/craft-parts#1243 (confidence 88%)

    maven plugin sibling issue from the same triaged batch; consolidated tracking would avoid duplicating effort.
