lucene Field.Index.ANALYZED不工作inVersion.LUCENE_40

Question

我是lucene的新手，我想要索引和搜索文件名，一个url给出任何可能的答案。

我的代码如下：

IndexWriter writer = null;
Analyzer analyzer = new StandardAnalyzer();
FSDirectory dir = FSDirectory.open(index);
IndexWriterConfig config = new IndexWriterConfig(Version.LUCENE_40, analyzer);
writer = new IndexWriter(dir, config);
Document doc = new Document();
doc.add(new Field("file_name", rs.getString("file_name"), Field.Store.NO,Field.Index.ANALYZED));
writer.addDocument(doc);
writer.optimize();
writer.commit();
writer.close();

，但在运行时会出现异常：

Exception in thread "main" java.lang.AbstractMethodError: org.apache.lucene.analysis.TokenStream.incrementToken()Z
at org.apache.lucene.index.DocInverterPerField.processFields(DocInverterPerField.java:133)

这和Lucene无关。您有一些运行时错误。AbstractMethodError方法错误javadoc声明：

Thrown when an application tries to call an abstract method. Normally, this error is caught by the compiler; this error can only occur at run time if the definition of some class has incompatibly changed since the currently executing method was last compiled.

查看运行应用程序时使用的库。
