我正在尝试使用CouchDB与JAVA。这是可怕的！！！这里的代码，我发现在网上：

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：

Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/http/impl/client/cache/CacheConfig
    at org.ektorp.http.StdHttpClient$WithCachingBuilder.withCaching(StdHttpClient.java:533)

我刚刚添加了一些.jar，因为控制台给我错误，如'ClassNotFoundException'，但这次我找不到要添加的.jar文件。有人链接下载.jar或任何其他解决方案吗？
PS：我在Windows10上使用Eclipse，如果它相关的话
在添加剩余的.jar之后，我发现了以下错误：
