Summary: Option to override parent breadcrumbs and links
Key: DOXIASITETOOLS-330
URL: https://issues.apache.org/jira/browse/DOXIASITETOOLS-330
Project: Maven Doxia Sitetools
Issue Type: Improvement
Components: Site model
Affects Versions: 2.0.0-M16
Reporter: Alexander Kriegisch
I have a use case in which I want to use a parent POM, because its defined
dependencies and plugins are exactly what I need. However, the parent POM has a
{{site.xml}} attached which I would like to completely replace, not inherit. As
that does not seem to be possible, at least I need to override some existing
entries of the site structure. While some like {{bannerLeft}} can just be
redefined, there is no way to remove them completely. Especially annoying in my
use case is the fact that I cannot override parent breadcrumbs.
As you can see
[here|https://github.com/apache/maven-doxia-sitetools/blob/5fe4a4c5359e6a23b78f385e15f77767cadaee99/doxia-site-model/src/main/java/org/apache/maven/doxia/site/inheritance/DefaultSiteModelInheritanceAssembler.java#L163-L164]
and

method {{‎DefaultSiteModelInheritanceAssembler::mergeLinkItemLists}} only
permits limited interactions with parent breadcrumbs, i.e. I can copy the first
one (which I want to get rid of, too) and cut off after that. But this is not
what I need.
What I need at least, is to be able to use something like {{<breadcrumbs
combine.self="override">}}, similar to Maven plugin configurations. Better
still would be an option to use that in all tags on all levels or an option
exposable to Maven Site to generally ignore a parent {{site.xml}}.
