JavaFX 11 jar不可执行java.lang.noClassDefFounderRorr：JavaFX/application/application

Question

Error: Could not find or load main class 
Caused by: java.lang.NoClassDefFoundError: javafx/application/Application

--module-path %PATH_TO_FX%
--add-modules javafx.controls,primary.fxml

java.lang.module.FindException: Module javafx.controls not found
Command execution failed.

或

    cd C:\Users\TCN\Documents\NetBeansProjects\testJavaFX; 
"JAVA_HOME=C:\\Program Files\\AdoptOpenJDK\\jdk-11.0.11.9-hotspot" cmd /c "\"
C:\\Program Files\\NetBeans-12.2\\netbeans\\java\\maven\\bin\\mvn.cmd\"

-Prelease-profile process-classes org.codehaus.mojo:exec-maven-plugin:3.0.0:exec"

The syntax of the command is incorrect.

我在Mac和Windows机器上都尝试了这个，结果是一样的。

我猜程序找不到JavaFX。

我的JDK是jdk-11.0.11.9-hotspot

在我安装了JDK11之后，我以前的jdk8 javafx项目现在也不会运行了。

我尝试将maven中的所有javafx JAR添加到我的POM中，同样，我只能从NetBeans中运行它。

同样，来自JDK8和JDK11的应用程序在NetBeans中都运行良好，但都不能从jar或Shell中运行。以前可以执行的jdk8中的旧JavaFX JAR现在不是了。

请问有人有解决办法吗？

相反，您可以将所有javafx模块作为maven依赖项加载，并使用一个Launcher类扩展主类并执行主函数。我已经写了一整篇关于这个的媒体文章。去看看。
