如何解决java jackess依赖错误?

Question

我试图显示MS Access数据库的数据，我使用的是jacess库，但我得到了一个依赖错误，我不知道如何解决。下面是我的代码和错误:

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();
         }
     }
 }

这是我的错误:

Answer 1

Commons Lang 3不向后兼容2.x。你必须下载2.6.

您可能还想研究Maven或Ant+Ivy，以使这种依赖解析更容易一些。

Answer 2

找到了;-)commons lang在类路径中，但它似乎是错误的版本。请求的包是org.apache.commons.lang.builder，它对commons-lang 2有效。在commons-lang3中，包是'org.apache.commons.lang3.builder'。因此，您必须包含一个公共语言2。x
