A module error occurred while running the JavaFX media application

When I run a JavaFX 11 application with the following command:

As far as I know, there is a problem with my module settings for this exception, but I don't know what I need to change:
>Add add INS to – add modules, which? > Add – add - open to command with module > something completely different?
Solution
JavaFX 11 is divided into seven modules On the command line, you have:
--add-modules javafx.controls,javafx.graphics
And the mistake you get is:
java.lang.IllegalAccessError: class com.sun.media.jfxmediaimpl.NativeMediaManager (in unnamed module @0x4d7be377) cannot access class com.sun.glass.utils.NativeLibLoader (in module javafx.graphics) because module javafx.graphics does not export com.sun.glass.utils to unnamed module @0x4d7be377
It tells you com sun. media. A class in the jfxmediaimpl package is in an unnamed module and attempts to access JavaFX Internal member of graphics module The name of the package indicates that it belongs to JavaFX Media module However, this error indicates that you are using JavaFX. Net in the classpath Media module You need to include JavaFX in the – add modules command Media to use it in the module path:
--add-modules javafx.controls,javafx.graphics,javafx.media
This is due to JavaFX Graphics module info file It has qualified export and / or open instructions that allow JavaFX Media accesses these internal packages However, if everything involved is on the module path, the module system can only consider these instructions
In the related instructions, you do not need to include JavaFX. Java in the command Graphics, because you have added JavaFX controls. javafx. Controls and JavaFX Both media require JavaFX Graphics and JavaFX Base modules, so they are pulled in
When or if you modularize your code, you won't have to deal with – add modules You only need to declare the corresponding requires Directive:
module example {
requires javafx.controls; // transitively requires javafx.base and javafx.graphics
requires javafx.media; // transitively requires javafx.base and javafx.graphics
// ... other directives ...
/*
* Don't forget to "exports" the package containing your Application
* class to at least the javafx.graphics module.
*/
}
Then you must ensure that all modules, including your module, are on - module path (or - P) Your module will introduce the necessary dependencies
java -p <other-modules>;<javafx-modules>;<your-module> -m <your-module>/<main-class>
