Hello, As one told me hibernate-search maven support should be considered as an Alpha version. So as I am using maven and hibernate-search 3.1.0Beta1 and trying to make it work I'd like to point out that this dependency is apparently missing (for me) : <dependency><!-- Is missing in hibernate-search 3.1.0.Beta1's pom --> <groupId>org.hibernate.apache.lucene.solr</groupId> <artifactId>apache-solr-analyzer</artifactId> <version>1.2.0</version> </dependency> If I don't include this dependency in my Maven POM I get the following error : java.lang.NoClassDefFoundError: org/apache/solr/analysis/TokenizerChain So if it can help...
