（Maven项目）无法找到或加载主类“类”

我正在按照春天的教程和一切工作正常，直到我克隆我的项目，现在克隆项目和原始项目不想工作，我已经搜索槽整个堆栈溢出类似的问题，我无法解决问题，我已经清理项目，重新启动日食，更新，添加并从pom.xml中删除依赖项，似乎没有任何工作。（Maven项目）无法找到或加载主类“类”

这里是我的主类：

package com.caveofprogramming.spring.test; 

import java.util.ArrayList; 
import java.util.List; 

import org.springframework.context.ApplicationContext; 
import org.springframework.context.support.ClassPathXmlApplicationContext; 
import com.caveofprogramming.spring.test.Offer; 
import com.caveofprogramming.spring.test.OfferDAO; 


public class Tester { 

    public static void main(String[] args) { 



     ApplicationContext context = new ClassPathXmlApplicationContext(
       "com/caveofprogramming/spring/test/beans/beans.xml"); 

     OfferDAO offersDao = (OfferDAO) context.getBean("offerDao"); 



     try { 

      List<Offer> offers= new ArrayList<Offer>(); 
      offers.add(new Offer(1,"Pepito", "[email protected]", "i know css and html5")); 
      offers.add(new Offer(2, "Juancito", "[email protected]", "i know about rest and play")); 
      offers.add(new Offer(3, "Juancho Tazo", "[email protected]", "im an expert on SPEL and SQL!")); 

      if(offersDao.Create(offers).length==offers.size()){ 

       for (int i = 0; i < offers.size(); i++) { 

        System.out.println(offers.get(i).getName()+" record was created succesfully"); 

       } 

       System.out.println("All the new records were created succesfully"); 

      } 

      else{ 
       System.out.println("One or more of the records were not createdS"); 
      } 

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

     ((ClassPathXmlApplicationContext) context).close(); 

    } 

}

的beans.xml：

使我说，当我复制粘贴项目在我的同一个工作区，一切都开始失败，当然我改变了名字。

这个错误我得到它后做一个maven干净。

如果我不这样做，我得到错误：喜欢你缺少类EventListenerFactory

正如你看到here自4.2以来增加的那样，尝试将pom.xml中的所有弹簧依赖项更新为4.2.5.RELEASE。

嘿，非常感谢，我更新了所有春天的依赖到4.0版本，它现在可以工作！谢谢！ –

看起来。在Maven 假象 org.springframework 春天上下文

定义它添加在你的pom.xml 使用相同的版本，为您的春季的其他文物依赖这个假象。

嗨，似乎错误出现时，我尝试添加tx名称空间的模式。一样，在beans.xml中，当添加：的xmlns：TX = “http://www.springframework.org/schema/tx” 和的xsi：的schemaLocation = HTTP：// WWW。 springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.1.xsd 当我删除它们时，程序再次正常工作，但是当我将它们添加回来时，程序抛出OP上提到的错误。 –
