Yegor Borovikov commented on MNG-6450:
--------------------------------------
[~joehni], thank you for looking at it! Currently Maven does allow attaching
classified pom artifacts to a project - the proposed change is about allowing
to use them in dependency management import context.
I'm not sure if pom-importing code would try to impose the main pom
dependencies on it somehow. However, you're right about other things being
involved - e.g. current DefaultModelBuilder implementation would simply ignore
the classifier (effectively importing the main pom instead).
How likely, in your opinion, is this enhancement to be approved for
implementation? I could continue to look further into the changes required for
it to actually work - it if it's not an obvious dead end.

> 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.
