【问题描述】：
我 我将 Apache Lucene 4.9 与 NetBeans 7.2 一起用于桌面应用程序。 我创建了一个标准分析器，因此想使用分析器 创建 IndexWriterConfig。但是他的 InexWriterConfig 给出了一个 class not found 错误
这是代码 sn-p。
// create some index
StandardAnalyzer analyzer = new StandardAnalyzer(Version.LUCENE_4_9);
System.out.println("index writer to be created1");
IndexWriterConfig IWConfig = new IndexWriterConfig(Version.LUCENE_4_9,analyzer);
这是IDE给出的错误

我最近遇到了一个类似的问题，该接口在 3.6.2 和 4.9.0 之间的某个时间从 lucene-core 中删除。尝试旧版本，看看是否能解决问题。
