在使用Lucene7时创建索引目录的时候，创建索引输出流，会遇到权

public class IndexManager {
    //创建索引库
    @Test
    public void createIndex() throws Exception {
        //1.采集数据
        titleInitializer titleInitializers = new titleInitializer();
        titleInitializers.titleInit();

        //文档集合
        List<Document> documentList = new ArrayList<>();

        //2.创建文档
        for (String article :
                titleInitializer.stringListHashMap) {
            Document document = new Document();
            //2.1创建域对象，加入文档对象
          /*  document.add(new TextField("locations", article.getLocations().toString(), Field.Store.YES));*/
            if (article != null){
                document.add(new TextField("title", article, Field.Store.YES));
                documentList.add(document);
            }
        }

        Directory directory = FSDirectory.open(Paths.get("D://indexDir"));

        IndexWriterConfig config = new IndexWriterConfig(analyzer);

        IndexWriter indexWriter = new IndexWriter(directory, config);
        //7.写入文档到索引库
        for (Document document : documentList) {
            indexWriter.addDocument(document);
        }
        //8释放资源
        indexWriter.close();
    }
}

索引目录是放在D盘下的一个文件夹，代码使用idea运行，报错信息如下：
