Eclipse rcp 无法在RCP视图中创建GEF实例

这是关于我需要在RCP应用程序中使用GEF的自动化

在其中一个视图中，我必须创建一个GEF实例，但如果我尝试创建这些实例，它会抛出错误，说无法实例化视图

这是错误转储

您找到错误了吗？没有，我找不到错误。我被打动了。查看转储后，我的想法是“我会导入一个不包含EditPartFactory类定义的gef jar文件”对此的任何注释否，我无法找到错误。我被打动了。在查看转储之后，我的想法是“我会导入一个不包含EditPartFactory类定义的gef jar文件”，并在上面添加任何注释this@Ravi：嗯，第一：您的Eclipse中是否安装了GEF插件？是的，我已经安装了。如果它不是他们的插件，那么当我尝试导入GEF时，它将抛出编译错误package@VonC-已安装v3.6.1，我已重新检查again@Ravi：我在最近的GEF版本（）中没有看到该类

EditPartFactory

。也许它已经搬到别处去了？
