删除索引报IO错误 couldn't delete commit.lock

[swj_20]

File files = new File(indexRelativePath);
Directory directory = FSDirectory.getDirectory(files, false);
Term term = new Term(field, text);
IndexReader reader = IndexReader.open(directory);
//这里记得要先解锁
Indexreader.unlock(directory);
int i = delete = reader.delete(term);
现在在Indexreader.unlock(directory);这一步报错java.io.IOException: couldn't delete commit.lock
indexRelativePath为E:\\java_work\\websearch\\indexFile
