检查solr / home属性和日志。 ClassCastException：类org.apache.lucene.analysis.icu.ICUFoldingFilterFactory

Question

一旦我开始Eclipse告诉他solr在哪里

`-Dsolr.home=D:\devel\apps\solr-4.3.1_master\ec2`

启动solr但出现以下异常。

我是solr的新手，对此话题我有点迷茫。 有没有人看起来可以帮助我解决问题的任何东西。

提前致谢

好 。 我发现了问题。 问题是我在solr / lib文件夹和Apache Tomcat / lib文件夹中复制了“ lucene-analyzers-icu-4.3.1.jar”和“ lucene-analyzers-smartcn-4.3.1.jar”。 。 我删除了tomcat中的那些。
