我想创建一个使用 GEF4 的Eclipse4应用。更准确地说，我想在我的应用中使用GEF4 MVC Logo Example 来源。我已经导入了GEF4源，编译还可以。但是当我想引用示例视图时，或者我尝试使用我的自定义代码时;我有运行时错误......

如果有人能为我提供整合GEF4示例的任何流程，那就非常好了
答案 0 :(得分：0)
如https://bugs.eclipse.org/bugs/show_bug.cgi?id=372171中所述，独立的MVC和MVC.FX包仍然依赖于org.eclipse.core.commands，而集成包MVC.UI和MVC.FX.UI另外引入了依赖关系org.eclipse.ui，org.eclipse.ui.views，org.eclipse.ui.workbench等（它们是兼容层的一部分）。 MVC徽标示例取决于所有这些。也就是说，目前无法将示例集成到纯e4应用程序（没有兼容层）中。
将独立软件包中的依赖项替换为带有e4链接的org.eclipse.core.commands（IMHO尚未在相应的范围内提供）将使这些软件包可以在本机e4应用程序中使用（即没有兼容层）。
对于集成包，必须完成相同的操作，而当前的集成主要基于兼容性层，因此可能需要更多的努力。这是需要进一步调查的事情。
