乾淨構建失敗在NetBeans

創建在NetBeans IDE的項目6.9 在一個項目中，我有一個接口IBusinessLogic 在第二個項目中，我創建了一個類BusinessLogic它實現IBusinessLogic 在第三個項目我創建BusienssLogic的對象並將此對象分配給IBusinessLogic的引用。我沒有得到任何錯誤而寫，但是當我清理並生成第三項目中，我得到異常，下面：乾淨構建失敗在NetBeans

 
incompatible types 
found : com.abc.businesslogic.BusinessLogic 
required: com.abc.businesslogic.interfaces.IBusinessLogic 
       com.abc.businesslogic.interfaces.IBusinessLogic logic = bl;

D:\ProjectsFeb12\Service\nbproject\build-impl.xml:531: The following error occurred while executing this line: 
D:\ProjectsFeb12\Service\nbproject\build-impl.xml:261: Compile failed; see the compiler error output for details. 
BUILD FAILED (total time: 3 seconds)

當我知道我可以指定在超類型的基準子類型的對象，那麼這異常必須是IDE。我該如何解決這個問題？我把我的所有代碼都移到了一個新項目中，但沒有成功。

代碼：

 
package com.abc.workerhandlers; 

import com.abc.businesslogic.BusinessLogic; 
import com.abc.businesslogic.interfaces.IBusinessLogic; 

public class MQ2MQWorker1 { 

    MQ2MQWorker1(){} 

    public void init(){ 

       BusinessLogic bl = new BusinessLogic(); 
       IBusinessLogic logic = bl; // This line is giving problem 
    } 
}

當我運行它完美地執行該項目，但該項目的罐子在dist目錄中沒有創建。

你可以發佈一段代碼的錯誤所在出現？ – 2012-03-27 06:21:51

您確定'com.abc.businesslogic.BusinessLogic'實現了'com.abc.businesslogic.interfaces.IBusinessLogic'嗎？ – 2012-03-27 06:21:53

@JimGarrison我確定。 – sjain 2012-03-27 06:30:15

你確定類路徑中有正確的類嗎？順便說一句，你不應該寫

BusinessLogic bl = new BusinessLogic(); 
IBusinessLogic logic = bl; // This line is giving problem

而只是IBUsinessLogic logic = new BusinessLogic();
