JavaFX

Download JavaFX (opens in a new tab) and extract it locally to {JAVAFX_PATH}: /Users/user/javafx-sdk-24, for example.

Code

Import JavaFX’s components (all the *.jar files under lib) into your project as referenced libraries. This will update .vscode/settings.json:

.vscode/settings.json

{
  "java.project.sourcePaths": ["src"],
  "java.project.outputPath": "bin",
  "java.project.referencedLibraries": [
    "lib/**/*.jar",
    "{JAVAFX_PATH}/lib/**/*.jar"
  ]
}

Create .vscode/launch.json using the Run and Debug view, then update your configuration with the following settings:

.vscode/launch.json

{
  "version": "0.2.0",
  "configurations": [
    {
      "type": "java",
      "name": "Application",
      "request": "launch",
      "mainClass": "App",
      "vmArgs": "--module-path {JAVAFX_PATH}/lib --add-modules javafx.controls"
    }
  ]
}

Launch the newly created configuration by selecting it from the dropdown menu in the Run and Debug view then running it using Start Debugging (F5).

IDEA

Follow the Create a new JavaFX project (opens in a new tab) guide from JetBrains.

Eclipse

Follow the Getting Started with JavaFX (opens in a new tab) guide from OpenJFX:

Open the marketplace using Help → Eclipse Marketplace then search for and install the e(fx)clipse (opens in a new tab) plugin. Agree to the license terms and wait—this will take a while—until you receive a message asking you to restart Eclipse to apply the update.
Select Settings → JavaFX then specify the location of the JavaFX directory ({JAVAFX_PATH}) in JavaFX 11+ SDK.
Select Settings → Java → Build Path → User Libraries then click on New to create a new user library named JavaFX. Click on Add External JARs and select all the *.jar files under {JAVAFX_PATH}/lib and add them.
Select Project → Properties → Java Build Path → Libraries → Modulepath then Add Library → User Library and select JavaFX.
Select Settings → Run/Debug → String Substitution and create a new variable FX_PATH with the value {JAVAFX_PATH}/lib.
Select Run → Run Configurations → Java Application → Arguments, set VM Arguments to --module-path ${FX_PATH} --add-modules javafx.controls and uncheck Use the -XstartOnFirstThread argument when launching with SWT.

Sample

Main.java

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.layout.BorderPane;
import javafx.stage.Stage;
 
public class Main extends Application {
  @Override
  public void start(Stage primaryStage) {
    try {
      BorderPane root = new BorderPane();
      Scene scene = new Scene(root, 400, 400);
      primaryStage.setScene(scene);
      primaryStage.show();
    } catch (Exception e) {
      e.printStackTrace();
    }
  }
 
  public static void main(String[] args) { launch(args); }
}
