代码可以与java实现一起使用，但不能与android一起使用。是否有任何方法可以使用Gradle依赖项来避免此类错误。

要在Android中使用Lucene，您可以：

使用Lucene 7.3.0的修改（请参阅以下答案：https://stackoverflow.com/a/76719236/22251021）的数据库
扩展org.apache.lucene.store.BaseDirectory：

package com.texopher.gophoxes;

import java.io.IOException;
import java.nio.file.Path;
import java.util.Collection;
import java.util.List;
import java.util.UUID;

import org.apache.lucene.store.BaseDirectory;
import org.apache.lucene.store.IOContext;
import org.apache.lucene.store.IndexInput;
import org.apache.lucene.store.IndexOutput;
import org.apache.lucene.store.LockFactory;

public class BucketDirectory extends BaseDirectory {

    protected Bucket bucket;
    
    public BucketDirectory(Bucket bucket, LockFactory lockFactory) {
        super(lockFactory);
        this.bucket = bucket;
    }

    @Override
    public void close() throws IOException {
    }

    @Override
    public IndexOutput createOutput(String name, IOContext context) throws IOException {
        return new BucketIndexOutput(bucket, name);
    }

    @Override
    public IndexOutput createTempOutput(String prefix, String suffix, IOContext context) throws IOException {
        return new BucketIndexOutput(bucket, prefix + UUID.randomUUID().toString().replaceAll("-", "") + suffix);
    }

    @Override
    public void deleteFile(String name) throws IOException {
        try {
            bucket.deleteFile(name);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    @Override
    public long fileLength(String name) throws IOException {
        try {
            return bucket.fileLength(name);
        } catch (Exception e) {
            e.printStackTrace();
        }
        return 0;
    }

    @Override
    public String[] listAll() throws IOException {
        String[] tag = new String[0];
        try {
            List<String> tmp = bucket.listFiles();
            tag = new String[tmp.size()];
            for (int i = 0; i < tmp.size(); i++) {
                tag[i] = tmp.get(i);
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
        return tag;
    }

    @Override
    public IndexInput openInput(String name, IOContext context) throws IOException {
        try {
            return new BucketIndexInput(bucket, name);
        } catch (Exception e) {
            e.printStackTrace();
        }
        return null;
    }

    @Override
    public void rename(String source, String dest) throws IOException {
        try {
            bucket.rename(source, dest);;
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    @Override
    public void sync(Collection<String> arg0) throws IOException {
    }

    @Override
    public void syncMetaData() throws IOException {
    }

}

使用以下代码进行搜索：

Query qr = new TermQuery(new Term("code", this.md5(link)));
Bucket bk = new Bucket(this.gopherServer, this.hole, this.magic);
Directory indexDirectory = new BucketDirectory(bk, new SingleInstanceLockFactory());
IndexReader reader = DirectoryReader.open(indexDirectory);
IndexSearcher searcher = new IndexSearcher(reader);
TopDocs docs = searcher.search(qr, 1);
ScoreDoc[] hits = docs.scoreDocs;
