错误：Eclipse插件导出中的“导入javafx.embed.swt无法解析”
我正在尝试导出Eclipse插件。 这只是我在这里通过示例创建的一个Eclipse视图： http ： //help.eclipse.org/mars/index.jsp？nav =％2F2_0
虽然插件运行正常，但我在导出时遇到以下错误（作为可部署的插件和片段）：
# 12/15/15 8:58:14 AM CET # Eclipse Compiler for Java(TM) v20150902-1521, 3.11.1, Copyright IBM Corp 2000, 2015. All rights reserved. ---------- 1. ERROR in C:\temp\[...].java (at line 22) import javafx.embed.swt.FXCanvas; ^^^^^^^^^^^^^^^^ The import javafx.embed.swt cannot be resolved 我试图通过将javafx.embed.swt添加到MANIFEST.MF中导入的包来解决这个问题，但这没有帮助。 我还检查了项目的插件依赖项，并在那里列出了jfxswt.jar。
同时我能够通过function和更新站点项目导出，但错误仍然存在。 我可以打开视图，但它没有显示任何内容。 关闭视图时，会显示空指针exception。 查看日志这仍然是由缺少的java.embed.swt引起的。

对我来说，它有助于将jfxswt.jar添加到Runtime类路径中。
相关文章： javafx包javafx.embed.swt不在java8u5中
转到Window> Preferences> Java> Installed JRE选择项目中使用的JRE选择Edit然后复制“JRE home path”并单击Add External JARs ...导航到复制的路径（例如/ usr / lib / jvm / java-8-openjdk-amd64）然后到jre /（如果它是一个jdk）lib文件夹并选择jfxswt.jar。 然后在Finish和Apply中 ，Eclipse将重建您的项目并将jar添加到“JRE System Library”。
这样做的好处是您无需修改所有项目。
在Neon中，在安装e(fx)clipse ，我不得不手动添加jar文件以使其工作（现在经历了多次，在Linux（Ubuntu）和OSX上）。
您也可以只安装e（fx）clipse ，这在此上下文中无论如何都是有用的。
