lucene Field.Index.ANALYZED在inVersion.LUCENE_40中不起作用

Question

我是Lucene的新手，我想索引和搜索URL的文件名給出任何可能的答案。

我的代碼如下：

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();

但是在運行時會出現異常：

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

這與Lucene無關。 您有一些運行時錯誤。 javadoc的AbstractMethodError方法錯誤指出：

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.

在運行應用程序時查看正在使用的庫。
