如何在 Java 中修复“模块 javafx.graphics 不会“打开 com.sun.javafx.text”到未命名模块”的问题？

Question

I am using

jdk12,javafx12

and eclipse ide. When I run my code it should create a pane a textfield and some buttons. It just creates the pane and then I get an error

I tried using

jdk11

I got the same error

I wrote these to

VM

arguments:

 --module-path /home/beyza/openjfx-12.0.1_linux-x64_bin-sdk/javafx-sdk- 12.0.1/lib --add-modules javafx.controls --add-modules javafx.base --add-modules javafx.graphics --add-modules javafx.fxml --add-modules javafx.media --add-exports javafx.graphics/com.sun.javafx.util=ALL-UNNAMED --add-exports javafx.graphics/com.sun.javafx.sg.prism=ALL-UNNAMED --add-exports javafx.graphics/com.sun.javafx.scene=ALL-UNNAMED --add-exports javafx.graphics/com.sun.javafx.util=ALL-UNNAMED --add-exports javafx.base/com.sun.javafx.logging=ALL-UNNAMED --add-exports javafx.graphics/com.sun.prism=ALL-UNNAMED --add-exports javafx.graphics/com.sun.glass.ui=ALL-UNNAMED --add-exports javafx.graphics/com.sun.javafx.geom.transform=ALL- UNNAMED --add-exports javafx.graphics/com.sun.javafx.tk=ALL-UNNAMED --add-exports javafx.graphics/com.sun.glass.utils=ALL-UNNAMED --add-exports javafx.graphics/com.sun.javafx.font=ALL-UNNAMED --add-exports javafx.graphics/com.sun.javafx.application=ALL-UNNAMED --add-exports javafx.controls/com.sun.javafx.scene.control=ALL- UNNAMED --add-exports javafx.graphics/com.sun.javafx.scene.input=ALL-UNNAMED --add-exports javafx.graphics/com.sun.javafx.geom=ALL-UNNAMED --add-exports javafx.graphics/com.sun.prism.paint=ALL-UNNAMED --add-exports javafx.graphics/com.sun.scenario.effect=ALL-UNNAMED --add-exports javafx.graphics/com.sun.javafx.text=ALL-UNNAMED --add-exports javafx.graphics/com.sun.javafx.geom=ALL-UNNAMED --add-exports javafx.graphics/com.sun.javafx.scene.text=ALL-UNNAMED --add-opens javafx.graphics/javafx.scene=ALL-UNNAMED --add-opens javafx.graphics/javafx.scene.text=ALL-UNNAMED

Here is my main class

I got this error

Exception in thread "JavaFX Application Thread" java.lang.ExceptionInInitializerError Caused by: java.lang.reflect.InaccessibleObjectException: Unable to make private int com.sun.javafx.text.PrismTextLayout.getLineIndex(float) accessible: module javafx.graphics does not "opens com.sun.javafx.text" to unnamed module

Answer 1

The right answer is --add-opens javafx.graphics/com.sun.javafx.text=ALL-UNNAMED to VM options.

But anyone can avoid those VM options if write a simple launcher class like this:

public class AppLauncher {
    public static void main(String[] args) {
        YourAppMainClassNameHere.main(args);
    }
}

And run the app through this.
