错误:缺少JavaFX运行时组件-JavaFX 11和OpenJDK 11和Eclipse IDE [英] Error: JavaFX runtime components are missing - JavaFX 11 and OpenJDK 11 and Eclipse IDE

问题描述

我有一个经典的问题:将JavaFX 11与OpenJDK 11以及Eclipse IDE一起使用.

I have this classical issue: Using JavaFX 11 with OpenJDK 11 together with Eclipse IDE.

Error: JavaFX runtime components are missing, and are required to run this application

我有OpenJDK 11.0.2

I have OpenJDK 11.0.2

dell@dell-pc:~$ java -version
openjdk version "11.0.2" 2019-01-15
OpenJDK Runtime Environment 18.9 (build 11.0.2+9)
OpenJDK 64-Bit Server VM 18.9 (build 11.0.2+9, mixed mode)
dell@dell-pc:~$ 

我也有JavaFX 11 SDK.顺便一提！如果您想知道的话，我正在使用Lubuntu Linux 18.10.

And I also have JavaFX 11 SDK. By the way! I'm using Lubuntu Linux 18.10 if you wonder.

然后，我将Eclipse IDE中JavaFX 11 SDK中的.jar文件包含到库包中.

Then I have included the .jar files from the JavaFX 11 SDK in Eclipse IDE into a library package.

然后，我已将此库软件包包含在我的JAdaptiveMPC项目中.

Then I have included this library package into my JAdaptiveMPC project.

我的代码语法没有错误，但是仍然无法编译我的项目.

I get no error in my code syntax, but still, I cannot compile my project.

你知道为什么吗?如果我从Maven导入所有这些.jar文件而不是下载JavaFX SDK并将其导入到库中，则会遇到相同的错误.

Do you know why? I got the same error if I import all those .jar files from Maven instead of download the JavaFX SDK and import it into a library.

继续

我已在Run Configuration

然后我尝试运行

仍然存在错误.

推荐答案

您的问题不是编译项目，而是运行它. 由于main是在Application扩展名中定义的，因此运行项目将在启动时在模块路径中需要JavaFX.

Your problem is not compiling the project, but running it. Since your main is defined in your Application-extension, running the project will require JavaFX in your module path on startup.

因此，要么将您的main外包到与Application不同的类中，要么添加带有VM参数的JavaFX模块:

So either outsource your main into a class different from your Application or add the JavaFX modules with VM arguments:

--module-path="<javafx-root>\lib" --add-modules="javafx.base,javafx.controls,..."
