java.lang.ClassNotFoundException：org.apache.http.impl.client.cache.CacheConfig

Question

我正在尝试将 CouchDB 与 JAVA 一起使用。 这太糟糕了：！！ 这是我在网上找到的代码：

package project.couchdb;

import java.net.MalformedURLException;
import org.ektorp.CouchDbConnector;
import org.ektorp.CouchDbInstance;
import org.ektorp.http.HttpClient;
import org.ektorp.http.StdHttpClient;
import org.ektorp.impl.StdCouchDbConnector;
import org.ektorp.impl.StdCouchDbInstance;
import org.ektorp.support.DesignDocument;


public class CouchConnect {

    public static void main(String[] args) throws MalformedURLException{

        //connection
        HttpClient client = new StdHttpClient.Builder().url("http://127.0.0.1:5984").build();
        CouchDbInstance dbIstance = new StdCouchDbInstance(client);

        //database
        CouchDbConnector db = new StdCouchDbConnector("test", dbIstance);
        db.createDatabaseIfNotExists();

        //document
        DesignDocument doc = new DesignDocument("test_doc");
        db.create(doc);
    }
}

错误：

我刚刚添加了一些.jar，因为控制台给了我类似“ClassNotFoundException”的错误，但这次我找不到要添加的.jar 文件。 有人下载.jar 或任何其他解决方案的链接吗？

PS：如果相关，我在 windows 10 上使用 eclipse

添加剩余的.jar 后，我有这个错误：

您的库列表中还需要 httpclient-cache。

宣布它“可怕”似乎还为时过早。
