ik-analyzer-solr5's Issues

solr5.1.0 JDK1.7环境下分词器出现

你好，系统为centos6.4、solr5.1.0 、JDK1.7编译后将ik-analyzer-solr5-5.x.jar放入到tomcat 的/lib目录下（步骤于README.md一致）。
首先出现java.lang.NoClassDefFoundError: org/apache/lucene/analysis/Analyzer错误，因此我将lucene-core-5.1.0.jar和lucene-analyzers-common-5.1.0.jar也一起放在了tomcat 的/lib目录下。加入之后重启tomcat又报这个错，请问是版本不兼容的缘故吗
