Java IllegalAccessError can't run Application

I'm setting up my first program for a class and I'm stuck on why my program won't run trying to debug. What do I need to do to debug this error?
I've tried to add libraries but this didn't seem to work.
import javafx.event.ActionEvent;
import javafx.event.EventHandler;
import javafx.scene.Parent;
import javafx.scene.Scene;
import java.io.IOException;
import javafx.fxml.FXMLLoader;
import javafx.scene.control.Button;
import javafx.scene.layout.StackPane;
import javafx.stage.Stage;
import java.awt.*;
public class Main extends Application {
#Override
public void start(Stage primaryStage) {
try{
Parent root = FXMLLoader.load(getClass().getResource("Sample.fxml"));
primaryStage.setTitle("My First JavaFX GUI");
Button button= new Button("Submit Answer");
StackPane layout= new StackPane();
layout.getChildren().add(button);
Scene scene1= new Scene(layout, 300, 250);
primaryStage.setScene(scene1);
primaryStage.show();
}
catch(Exception e)
{
e.printStackTrace();
}
}
public static void main(String[] args) {
launch(args);
}
}
This is the error my Run Console is giving me:

I expect this to run, but it won't and I'm really stuck on where to act.
Thanks for taking a look ! Any help is appreciated :D

Add the modules to your modulepath. Most projects just need javafx.controls and javafx.fxml but check to see if you need other packages.
Run > Edit Configuration > VM Options >
--module-path /path/to/javafx-sdk-13/lib --add-modules javafx.controls,javafx.fxml
Like so:
Additionally make sure that your SDK and project language level is properly setup in:
File > Project Structure > Project
Make sure that your OpenFX library is added (either manually or with something like Gradle) in:
File > Project Structure > Libraries
And one last thing, I don't think you meant to import java.awt.*; in your code.

Cannot access class com.sun.javafx.util.Utils (in module javafx.graphics) - JavaFX & Eclipse

I have follow this guide to setup JavaFX onto a Linux machine.
First I have installed Java 11
asus#asus-pc:/usr/share/openjfx/lib$ java -version
openjdk version "11.0.3" 2019-04-16
OpenJDK Runtime Environment (build 11.0.3+7-Ubuntu-1ubuntu219.04.1)
OpenJDK 64-Bit Server VM (build 11.0.3+7-Ubuntu-1ubuntu219.04.1, mixed
mode, sharing)
asus#asus-pc:/usr/share/openjfx/lib$
Then I have installed OpenJFX from the command sudo apt-get install openjfx
asus#asus-pc:/usr/share/openjfx/lib$ ls
javafx.base.jar javafx.graphics.jar javafx.swing.jar
javafx.controls.jar javafx.media.jar javafx.web.jar
javafx.fxml.jar javafx.properties src.zip
asus#asus-pc:/usr/share/openjfx/lib$
Then have created a library in Eclipse.
Then I have include it into my java project. I try to run this code:
package se.danielmartensson.start;
import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.stage.Stage;
public class Main extends Application{
/*
* Start the start(Stage front)
*/
public static void main(String[] args) {
launch();
}
#Override
public void start(Stage front) throws Exception {
Parent root = FXMLLoader.load(getClass().getResource("/JUSBPlotter/src/se/danielmartensson/fxml/front.fxml"));
Scene scene = new Scene(root);
front.setScene(scene);
front.setTitle("Fracken");
front.show();
}
}
And I have change the run configurations to:
But when I compile the code. I get this errors:

Exception running application se.danielmartensson.start.Main
Question:
Is there anyone where who know how to solve this error? I have setup JavaFX before, but this time, it won't work for me.
Edit 1:
If I change the run configurations to:
--module-path="/usr/share/openjfx/lib" --add-modules=javafx.controls,javafx.fxml
I get this errors

Having the same issue with IntelliJ IDEA 2020.1 with JDK 14.
Finally resolved by adding a module-info.java like this one under src/main/java if you use maven:
module sample {
requires javafx.controls;
requires javafx.graphics;
opens sample;
}

Go to Run>Run Configurations then Arguments tab and go to VM Arguments and paste the following code to add modules
"--module-path /path/to/lib --add-modules javafx.controls,javafx.fxml"
remember to modify /path/to/lib to your path your library
then click apply and you're set

thanks, works for me as follows
public void start(Stage primaryStage) throws Exception{
Parent root = FXMLLoader.load(getClass().getResource("sample.fxml"));
module-info.java:
module sample {
requires javafx.controls;
requires javafx.graphics;
requires javafx.fxml;
opens sample ;
}

Thank you igonejack. I did what you said but I faced some other exceptions after that, So I came up with below code:
module {pkg}{
requires javafx.controls;
requires javafx.graphics;
requires javafx.fxml;
exports {pkg of Application class};
opens {pkg};
}
after that you need to rebuild your project probably because of some exception about Kotlin.
Then I saw exception "location is not set". To solve this you must start fxml location with "/" such as:
App.class.getResource("/form.fxml");
Edit
I made a HelloWorld project at JavaFxHelloWorld using Gradle.

As marco-rosati proposed in #638 issue, if you are using maven you can simply add this plugin:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>3.0.0-M5</version>
<configuration>
<argLine> --add-exports javafx.graphics/com.sun.javafx.application=ALL-UNNAMED </argLine>
</configuration>
</plugin>

How to fix JavaFX IllegalArgumentError: cannot access class [duplicate]

I am totally new in javafx!!
I tried a very very simple code and I got stuck.
when I tried to add a button to the layout It does not work.
I know this question may be too simple but I really do not know how to fix it.
I would appreciated if you could help me.
This is my code:
import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.layout.StackPane;
import javafx.stage.Stage;
public class Test extends Application{
Button button;
public static void main(String[] args){
launch(args);
}
#Override
public void start(Stage stage) throws Exception {
stage.setTitle("Title");
StackPane layout = new StackPane();
button = new Button();
layout.getChildren().add(button);
Scene scene = new Scene(layout);
stage.setScene(scene);
stage.show();
}
}
and I got the error:

Exception running application Test

From the error I'm assuming you're using JavaFX 11 (or at least JavaFX 9+). Note that the ultimate problem is not the InvocationTargetException but the IllegalAccessError:
Caused by: java.lang.IllegalAccessError: superclass access check failed: class com.sun.javafx.scene.control.ControlHelper (in unnamed module #0x46b3f4cf) cannot access class com.sun.javafx.scene.layout.RegionHelper (in module javafx.graphics) because module javafx.graphics does not export com.sun.javafx.scene.layout to unnamed module #0x46b3f4cf
This is telling you code in the "unnamed module" is trying to access internals of the javafx.graphics module. As this is not allowed the error is thrown. But the real problem here is that ControlHelper is in the unnamed module but it's supposed to be in the javafx.controls module, if the package name is anything to go by. This problem is caused by having javafx.graphics on the modulepath but javafx.controls on the classpath.
Make sure you have both modules (and javafx.base) on the --module-path. As your code is not modular (no module-info file) you will also have to tell the module system to resolve it by using:
--add-modules javafx.controls
You don't have to include javafx.graphics in the --add-modules command because javafx.controls requires javafx.graphics (and javafx.graphics requires javafx.base). As all modules are on the modulepath they will be resolved.
How you set these commands is dependent on how you launch your application (e.g. command-line, IDE, Maven, Gradle, etc...).
If you ever make your code modular you won't need to use the --add-modules command, just put the appropriate requires directives in your module-info file. For example:
module app {
requires javafx.controls;
}

Code works fine, then after maven install, there are errors in both the jar and the IDE

Exception running application edu.citytech.view.EmployeeMain
Here's the class with the main method, EmployeeMain.java:
package edu.citytech.view;
import edu.citytech.utitlity.GlobalVariables;
import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.scene.image.Image;
import javafx.stage.Stage;
public class EmployeeMain extends Application {
#Override
public void start(Stage primaryStage) throws Exception {
Parent root = FXMLLoader.load(getClass().getResource("EmployeeView.fxml"));
primaryStage.setScene(new Scene(root));
primaryStage.show();
// * new *
primaryStage.setResizable(false);
primaryStage.setTitle("Employee List");
primaryStage.getIcons().add(new Image(EmployeeMain.class.getResourceAsStream("People.jpg")));
}
public static void main(String[] args) {
if (args.length > 0) {
GlobalVariables.portNumber = (Integer.parseInt(args[0]));
}
launch(args);
}
}
And what fixes this is adding a space to any of the files and saving it, then restarting the Eclipse IDE, and running it again from the IDE. What breaks it is when I run mvn clean and mvn install, and then running the jar file it created. Everyone in my class is having this problem, and the teacher has no idea how to fix it. It just works for some people and it doesn't for others. However this time, this isn't working no matter what I try. Only works in the IDE until I use maven to create a jar. Then it won't work until I modify and save a file, and then restart the IDE. Everything is named properly and it just works and doesn't work randomly. Is this an IDE problem or a project problem?
What can I do so that I can make a jar file that works when it's run?

I figured out how to get it to work. Really annoying but really simple. I'm going to write it here for anyone who is probably finding this page through a search engine.
Right click on project folder > Maven > Update Project...
Update selected project
Right click the project folder and run in local terminal
mvn install
And DO NOT DO MVN CLEAN

3 issues possible
it sounds like you need the IDE to recompile the code for it to work again in eclipse too? not sure why that would be actually unless its the java version used ...
eclipse usually rebuilds given any change (e.g. your space added to file)
is your eclipse IDE and maven compile are using the same java version?
delete your ./target directory and
add this to maven pom.xml to make sure you're using the right java version (e.g. for java 1.8):
<properties>
<maven.compiler.source>1.8</maven.compiler.source>
<maven.compiler.target>1.8</maven.compiler.target>
</properties>
include the file in the jar build
Also the copy your EmployeeView.fxml should be in src/main/resources and the file wont be making it into your jar file unless you include:
<resources>
<resource>
<directory>src/main/resources</directory>
<includes>
<include>**/*</include>
</includes>
</resource>
</resources>
That code won't work within the jar file at runtime see these answers:
How to reference a resource file correctly for JAR and Debugging?
and update your code to use getREsourceAsStream e.g. here's a method i use:
public void load(String resource, HashSet<String> hashset) {
ClassLoader classloader = Thread.currentThread().getContextClassLoader();
InputStream is_awl = classloader.getResourceAsStream(resource);
BufferedReader reader = new BufferedReader(new InputStreamReader(is_awl));
String line;
try {
while ((line = reader.readLine()) != null) {
hashset.add(line.trim());
}
} catch (IOException e) {
System.err.println("LexicalFeatures can't initialise:"
+ resource + " hashset: "+ e.getMessage());
e.printStackTrace();
}
}
