我需要从 GEF4 转到 Zest 2。我从 Eclipse 市场获得了 Zest2。但是,当我运行使用它的程序时,出现以下错误
Caused by: java.lang.ClassNotFoundException: org.eclipse.gef4.geometry.planar.Rectangle

我假设这意味着我也需要 GEF4 几何包,所以我尝试从 gef4 下载它 - http://download.eclipse.org/tools/gef/gef4/updates/integration 但是这是不允许的它说我缺少包 javafx.collections。
Cannot complete the install because one or more required items could not be found.
Software being installed: GEF4 Geometry JavaFX Conversion 0.1.0.201407251903 (org.eclipse.gef4.geometry.convert.fx.feature.group 0.1.0.201407251903)
Missing requirement: GEF4 Geometry JavaFX Conversions 0.1.0.201407251903 (org.eclipse.gef4.geometry.convert.fx 0.1.0.201407251903) requires 'package javafx.collections [2.0.0,3.0.0)' but it could not be found
Cannot satisfy dependency:
From: GEF4 Geometry JavaFX Conversion 0.1.0.201407251903 (org.eclipse.gef4.geometry.convert.fx.feature.group 0.1.0.201407251903)
To: org.eclipse.gef4.geometry.convert.fx [0.1.0.201407251903]
有人可以告诉我如何解决这个问题吗?谢谢。
