Yegor Borovikov commented on MNG-6450:
--------------------------------------
[~rfscholte], the idea is to automatically produce an up-to-date BOM with a
plugin as a part of a project build - instead of having to manually maintain it
(adding/removing modules, updating their versions, etc.).
Of course, the correctness of the generated BOM would be a responsibility of
the plugin (like that of any other artifacts produced by Maven plugins), and
nothing seems to prevent it from using a ModelValidator as an extra check.
Maven plugins are encouraged to attach classified artifacts only - hence this
issue.
On the bright side, currently a plugin can as easily attach any artifact to any
reactor module (and non-classified poms can be imported by any version of
Maven), so there's no pressing need for the change - beyond compliance with the
recommendation (introduced by 6cf9320942c34bc68205425ab696b1712ace9ba4) to use
MavenProjectHelper exclusively.
> Allow importing a POM with a classifier

> Key: MNG-6450
> URL: https://issues.apache.org/jira/browse/MNG-6450
> Project: Maven
> Issue Type: Improvement
> Components: Dependencies, POM
> Affects Versions: 3.0
> Reporter: Yegor Borovikov
> Priority: Major
> Labels: easy-fix, pull-request-available
>
> Currently, a POM-packaged artifact with a classifier cannot be imported -
> there is an explicit check for that in
> [DefaultModelValidator|https://github.com/apache/maven/blob/master/maven-model-builder/src/main/java/org/apache/maven/model/validation/DefaultModelValidator.java#L480].
> I couldn't find anything in Maven documentation that would mention/explain
> this limitation. According to [~rfscholte] this [might
> be|https://www.mail-archive.com/[email protected]/msg114101.html]
> "historical".
> Example use case: a BOM (bill of materials) plugin could generate a BOM POM
> and attach it (with a classifier) to the project. However, currently there's
> no way to import the generated BOM because of the restriction.
