I'm trying to enable clustering in solr 1.4. I'm following these instructions:
http://wiki.apache.org/solr/ClusteringComponent However, `ant get-libraries` fails for me. Before it tries to download the 4 jar files, it tries to compile lucene? Is this necessary? Has anyone gotten clustering working properly? My next attempt was to just copy contrib/clustering/lib/*.jar and contrib/clustering/lib/downloads/*.jar to WEB-INF/lib and enable clustering in solrconfig.xml, but this doesnt work either and I cant tell from the error log whether it just couldnt find the jar files or if there is some other problem: SEVERE: org.apache.solr.common.SolrException: Error loading class 'org.apache.solr.handler.clustering.ClusteringComponent'
