我如何解決java jackces依賴性錯誤？

我打算從MS Access數據庫顯示數據，我正在使用Jackcess庫，但我得到一個依賴性錯誤，我不知道如何解決。這裏是我的代碼和錯誤：我如何解決java jackces依賴性錯誤？

import com.healthmarketscience.jackcess.*; 
import java.io.*; 
import java.util.*; 
import java.sql.*; 
import java.nio.*; 
import java.lang.*; 
import org.apache.commons.*; 
import org.apache.commons.lang3.builder.*; 
import org.apache.log4j.Logger; 
import org.apache.log4j.xml.DOMConfigurator; 

class Main { 
    private static Logger log=Logger.getLogger(Main.class); 
    public static void main(String args[]) { 
     DOMConfigurator.configure("lib\\log4j.xml"); 
     try { 

      Database d = Database.open(new File("lib\\ExTables.mdb")); 
      System.out.println(d.getTable("Cliente").display()); 

     } catch(Exception e) { 
      e.printStackTrace(); 
     } 
    } 
}

這裏是我的錯誤：

這就是我的命令行：

你的classpath中是否有所有必需的jar？ CompareToBuilder屬於commons-lang。 – Andreas

感謝您回答Andreas！我不確定！在apache庫中是commons-lang？ – haltman

Apache有很多發佈庫的項目。包含你的類的庫的名字是commons-lang- Andreas

下議院郎3不與2.x的向後兼容你必須下載2.6。

您可能還想調查Maven或Ant + Ivy以使這種依賴關係解析更容易一些。

謝謝artbristol！降級圖書館解決我的依賴問題，但我得到一個nullpointerexception，我要研究爲什麼...大聲笑 – haltman

發現它;-) commons lang在類路徑中，但它似乎是錯誤的版本。請求的包是org.apache.commons.lang.builder，它對commons-lang3中的commons-lang 2.x有效，包是'org.apache.commons.lang3.builder'。所以你必須包含一個commons-lang 2.x
