Joerg Schaible commented on MNG-6450:
-------------------------------------

I am not sure, if we can really overview the consequences of this enhancement. 
While I understand the intention and often wished myself something like this, 
we have to face, that currently all attached artefacts of a component share the 
same dependencies i.e. the ones that are declared in the POM of the project. I 
have no idea at how many places this fact is currently silently taken for sure.

> Allow importing a POM with a classifier

> 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.
