Re: svn commit: r1604930 - in /maven/plugins/trunk/maven-dependency-plugin/src: it/mdep-450-project-with-ancestor/ it/mdep-450-project-without-ancestor/ main/java/org/apache/maven/plugin/dependency/ site/apt/
useful info
but couldn't it be added to dependency:tree, instead of a new goal?
here is actual output [1]
parents could be added before actual dependencies, in reverse order:
parent-of-parent
parent
pom
\- dependency
WDYT?
Regards,
Hervé

Hervé,
IMO tree is a completely different beast, to be honest having info about
the ancestors seems (now) so basic to me that I would even have this to be
a core feature. No remote lookups are used here whereas tree needs to do a
complete dependency resolution.
Regards
Mirko
