在 Eclipse Mars.1 上安装 e(fx)clipse 插件时出错 IDE

Question

我正在尝试在我的 eclipse mars.1(4.5.1) 上安装 eclipse 插件 e(fx)clipse。目前，当我转到“帮助”->“安装新软件...”时，将此 link (http://download.eclipse.org/efxclipse/updates-released/2.0.0/site) 粘贴到 "work with" 文本框中，单击该框以安装 "e(fx)clipse - install" ，然后单击下一步，我收到一条错误消息，指出：

Cannot complete the install because one or more required items could not be found.
Software being installed: e(fx)clipse - IDE 2.0.0.201506111511 (org.eclipse.fx.ide.feature.feature.group 2.0.0.201506111511)
Missing requirement: PDE UI Tooling 2.0.0.201506111511 (org.eclipse.fx.ide.pde.ui 2.0.0.201506111511) requires 'bundle org.eclipse.pde.ui.templates 3.4.400' but it could not be found

我不知道为什么会收到此错误消息，因为几周前我将它安装在笔记本电脑上并且运行良好。我用谷歌搜索了这个，所有出现的都是这样的错误，但仅限于以前版本的 Eclipse。请帮助并提前致谢

以下是一些屏幕截图：
