[ERROR] VM #displayTree: error : too few arguments to macro
-----------------------------------------------------------
Key: MSITE-170
URL: http://jira.codehaus.org/browse/MSITE-170
Project: Maven 2.x Site Plugin
Issue Type: Bug
Affects Versions: 2.0
Reporter: fabrizio giustina
when running mvn site:site a couple of "too few arguments to macro" always pop
up. This is extremely bad in terms of user experience, and we should find a way
to remove these logs:
[ERROR] VM #displayTree: error : too few arguments to macro. Wanted 2 got 0
[ERROR] VM #menuItem: error : too few arguments to macro. Wanted 1 got 0
These errors are due to a known velocity bug related to the use of recursive
macros:

PROTECTED]
Recursive macros are defined in
org/apache/maven/doxia/siterenderer/resources/default-site.vm in the doxia
site-renderer component.
Logging is handled in the plexus velocity component.
This velocity bug is still open in velocity and no patch will be available
anytime soon. In the meanwhile we should try to handle this situation in some
way by filtering out messages or removing the use of recursive macros (very
hard, they are used to print out the site tree)... or switching to a better
templating engine like freemarker.
This issue could probably be addressed in the plexus velocity component or in
the doxia site renderer (given that waiting for a bugfixed velocity release is
not an option). I'm anyway assigning it to the site plugin since it's where
users see these logs coming from and where probably users could open similar
issues.
Any suggestion on how to dirty-patch this?
