[MNG-8539] MavenProject.getArtifacts() always returns file path in with default path pattern

**[Konrad Windszus](https://issues.apache.org/jira/secure/ViewProfile.jspa?name=kwin)** opened **[MNG-8539](https://issues.apache.org/jira/browse/MNG-8539?redirect=false)** and commented

In Maven 3.x the file path returned for `MavenProject.getArtifacts()...getFile()` always considered the actually attached file names (i.e. considering the `project.build.finalName`, https://maven.apache.org/pom.html#The_BaseBuild_Element_Set) while with Maven4 this always returns a file path in the project local repository which does not consider the `finalName`.
This may lead to subtle differences where the artifacts filename is used for other purposes as well.
