/ 25 мая 2020

У меня очень простой java код Lucene, который работает в моих друзьях P C, но он делает много ошибок для меня ... мы все используем Lucene 5.3.1, я думаю, что проблема в моем jdk11 

package project;
import java.io.IOException;

import java.nio.file.Path;
import java.nio.file.Paths;
import org.apache.lucene.analysis.standard.StandardAnalyzer;
import org.apache.lucene.document.Document;
import org.apache.lucene.document.Field;
import org.apache.lucene.document.IntField;
import org.apache.lucene.document.TextField;
import org.apache.lucene.index.IndexWriter;
import org.apache.lucene.index.IndexWriterConfig;
import org.apache.lucene.store.Directory;
import org.apache.lucene.store.FSDirectory;
public class Act1 {
public static void main(String[] args) throws
IOException {
Document doc = new Document();
Field titre = new TextField("Titre", "mon A staticestimation technique",Field.Store.YES);
Field ref = new IntField("Year", 2001,Field.Store.YES);
Field auteurs = new TextField("Auteurs","TaewhanKim, Ki-Seok Chung, C. L. Liu",Field.Store.YES);
doc.add(titre);
doc.add(ref);
doc.add(auteurs);
Path p = Paths.get("C:\\Users\\user\\Desktop\\abc");
Directory dir = FSDirectory.open(p);
StandardAnalyzer analyzer = new StandardAnalyzer();
IndexWriterConfig config = new IndexWriterConfig(analyzer);
IndexWriter index = new IndexWriter(dir, config);
index.addDocument(doc);
index.close();
}
}

но он делает эти ошибки
