如何在java中使用代碼將一個或多個包正確地移動到另一個包中

我正在開發一個應用程序[桌面擺動應用程序]，它需要我通過代碼進行重構。 [我知道的界面和功能已經由Eclipse IDE 提供，但我通過代碼來做到這一點需要如何在java中使用代碼將一個或多個包正確地移動到另一個包中

重構的第一階段，我需要做的是移動選擇套裝[選擇給出選項通過複選框使用JDT的想法顯示工作區中的所有可用軟件包。我在此位置使用教程：http://www.vogella.de/articles/EclipseJDT/article.html]

現在，我已經選擇了我想移動到另一個包的包，

我用這段代碼

233. for (IPackageFragment mypackage : packages) { 
234.     if ((mypackage.getKind() == IPackageFragmentRoot.K_SOURCE) && (searchifSelected(mypackage.getElementName())==true)){ 
235.      IJavaElement container = newModule.getPrimaryElement(); 
236.      mypackage.move(container, null, null, true, null); 
       } 
    }

searchifSelected（mypackage的.getElementName（））== true告訴我是否選擇了要移動的特定程序包

IJavaElement container = newModule.getPrimaryE字元素（）;是包含所選包的容器[新包]

mypackage.move（container，null，null，true，null）;就我看來，這個命令應該把「mypackage」移動到「container」作爲「孩子」。

不過，我面臨這個問題：

，我認爲我給了錯誤的論據手段。

有人可以幫我應該怎麼做嗎？

可以包括行號到您的代碼段.. – rana

我很抱歉，我沒有得到烏爾點？ – user

@ rana，我已添加行號 – user

對於那些誰[R面臨同樣的問題，我發現了另一種方式來做到這一點，即使用重命名方法，並使其發揮作用作爲移動功能。儘管它可能/可能不是最好的選擇。

我替換上面的代碼，此代碼

 for (IPackageFragment mypackage : packages) { 
       if ((mypackage.getKind() == IPackageFragmentRoot.K_SOURCE) && (searchifSelected(mypackage.getElementName())==true)){ 
        mypackage.rename(textfield.getText()+"."+mypackage.getElementName(), true, null); 
       } 
      }
