> -------------------------------------------

> Key: MNG-5871
> URL: https://issues.apache.org/jira/browse/MNG-5871
> Project: Maven
> Issue Type: Improvement
> Components: Inheritance and Interpolation
> Affects Versions: 3.3.3
> Reporter: Hervé Boutemy
> Assignee: Hervé Boutemy
> Fix For: 3.3.8

>
> currently, default urls calculated for child from parent values are often
> discussed
> but their implementation is no easy to find: it's a mix between
> - DefaultInheritanceAssembler.getChildPathAdjustment(, which calculates path
> adjustment
> - MavenModelBuilder.appendPath, that calculates the child url: in general,
> parent url is used, but if childpathadjustment is set, this is the algorithm
> to extrapolate child from parent
> IMHO, the test on childpathadjustement is a hack; in fact, we should use
> method overriding: default method just returns arent, but
> DefaultInheritanceAssembler.InheritanceModelMerger should override it with
> the extrapolation algorithm
> this would make the code a lot more clear and help for future enhancements
