导入org.apache.lucene.analysis.SimpleAnalyzer符号在Apache lucene中找不到错误

Question

大家好，我想在我的日志解析器项目中使用Apache Lucene。现在，我已经使用了波纹管代码，但我不能够导入org.apache.lucene.analysis.SimpleAnalyzer 我已经包括lucene4.1罐子

我说只有一个jar文件是Lucene的核心-4.1.0.jar。我无法导入样本分析器。因此，我无法创建索引编写器。我错过了什么。我是lucene新手

您还需要lucene-analyzers-common-4.1.0.jar。
