必需jar包含org/apache/lucene/analysis/standard/StandardAnalyzer丢失，所以你必须下载JAR（Lucene的-1.2.jar） ，然后设置你的classpath

Answer 2

I had the same problem today. When I check the error, I found org.hibernate.search on several lines, even though I'm just using the Hibernate ORM. Then I removed the build path of Hibernate Search and no more error. Check if you have the same path and if you don't need it, just remove it.
