如何使用代码将一个或多个包正确地移动到java中的另一个包中

我正在开发一个应用程序[桌面swing应用程序]，它需要我通过代码进行重构。[我知道eclipse IDE已经提供了接口和功能，但我需要通过代码来实现这一点

我需要做的重构的第一个阶段是移动选定的包[要选择的选项通过复选框给出，该复选框使用JDT的思想显示工作区中所有可用的包。我在这个位置使用了教程：]

现在我已经选择了我希望移动到另一个包的包

我使用了这段代码

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.getElementName（））==true告诉我是否已选择要移动的特定包

IJavaElement container=newModule.getPrimaryElement（）；是将包含所选包的容器[新包]

mypackage.move（container，null，null，true，null）；据我所知，这个命令应该将“mypackage”作为“child”移动到“container”

然而，我面临着这个问题：

我认为这意味着我给出了错误的论点

有人能帮我做些什么吗？

我在eclipse论坛[我使用的IDE]上发布了这个问题，然后发现这个问题/bug的方法无法在循环中工作。你必须一个接一个地显式调用这个函数。在这个链接中也报告了类似的bug：

[w.r.t delete method]

对于那些面临同样问题的人，我找到了另一种方法，即使用rename方法并使其作为移动函数工作。尽管它可能是/可能不是最好的选择

我用这个代码替换上面的代码

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

你能把行号包括到你的代码段中吗？对不起，我没有领会你的意思？@rana，我已经加了行numbers@carl：我之前提到过，我必须通过代码来完成这项工作，而不使用IDE的功能
