Hey;
I am just getting up and running with XWiki but am having some issues with
getting the Lucene Plugin to work. I have uncommented the following lines in
WEB-INF/xwiki.cfg:
#-# Lucene search engine
xwiki.plugins.lucene.indexdir=/tmp/xwiki/lucene
xwiki.plugins.lucene.analyzer=org.apache.lucene.analysis.standard.StandardAnalyzer
xwiki.plugins.lucene.indexinterval=20
And to do diagnostics I created a new page with just these lines of code:
{{velocity}}
#set($results = $xwiki.lucene.rebuildIndex())
{{/velocity}}
when I view the page, the macro fails. when I look at the output, i see this
(reduced):
org.xwiki.rendering.macro.MacroExecutionException: Failed to evaluate

It seems that it is throwing a NullPointerException. This is exactly what it
does when I try to rebuild the index on the XWiki provided Lucene Search
page as well.
Any ideas as to what I can do to solve this? Could it be a configuration
error?
