java - 如何使用代码将一个或多个包正确地 move 到java中的另一个包中

Question

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 已经提供了界面和功能但我需要通过代码来完成

我需要做的重构的第一阶段是 move 选定的包 [选择的选项是通过复选框给出的，该复选框使用 JDT 的思想在工作区中显示所有可用的包。我在这个位置使用了教程:http://www.vogella.de/articles/EclipseJDT/article.html ]

现在我已经选择了我希望 move 到另一个包的包，

这段代码我用过

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 告诉我是否选择了要 move 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); 据我阅读，此命令应该将“mypackage”作为“子项” move 到“容器” .

但是，我遇到了这个问题:

我认为这意味着我给出了错误的论点。

有人可以帮助我该怎么办吗？

我在 eclipse 论坛 [我正在使用的 IDE] 上发布了这个问题，然后发现这个问题/bug 与它在循环中不起作用的方法有关。您将必须逐一显式调用此函数。此链接中也报告了类似的错误:
