我做它像這樣和它的作品對我來說：

Directory directory = FSDirectory.open(folder); 
    if (directory.fileExists(IndexWriter.WRITE_LOCK_NAME)) { 
     directory.clearLock(IndexWriter.WRITE_LOCK_NAME); 
     log.warn("Existing write.lock at [" + folder.getAbsolutePath() + "] has been found and removed. This is a likely result of non-gracefully terminated server. Check for index discrepancies!"); 
    } 
    directory.close();
