JavaFX runtime components are missing, and are required to run this application on VSCode

A java newbie here. I wanted to learn about JavaFX on VSCode but when I launch my JavaFX it gave me this error. I tried to add referenced Library and the configurations vmArgs on launch.json on the project, but it giving me the same thing.

Here is my config.

"vmArgs": "--module-path C:/Users/vince/Downloads/javafx-sdk-17.0.1/lib --add-modules javafx.controls,javafx.fxml"

Can anyone help me please ?

  • Keep your project folder in Workspace and not in a subfolder in Workspace so you don't get the class not found error because the path of class file is sets "bin" as default in .vscode/settings.json file because of this if you try to access App.java file from subfolder in workspace then it throws error.
  • If you creates new java file in project then don't forgot to add the below line in .vscode/launch.json.

"vmArgs": "--module-path \"enter_the_path_here_of_lib(Refrenced_Library not lib present in your project folder)\" --add-modules javafx.controls,javafx.fxml"

If you still get this error after setup "vmAgrs", and your using debug/launch-(F5)-to start your App, its possible that VSCode wouldn't launch your "App.java" file, instead will try to launch "Current file" which is something else..

To fix it just change "Launch Current file" to "Launch App" from "Start debugging" in "Run and Debug" icon.

Anyway if any of this didn't work, you could Run it manually by:

1st compile using javac

javac --module-path "PATH\javafx-sdk-19.0.2.1\lib"  --add-modules javafx.controls App.java

2nd Run it..

java --module-path "PATH\javafx-sdk-19.0.2.1\lib"  --add-modules javafx.controls App

Solution: You simply need some edits in your "vmAgrs" in the "launch.json" file

"vmArgs": "--module-path \"C:/Users/vince/Downloads/javafx-sdk-17.0.1/lib\" --add-modules javafx.controls,javafx.fxml"

General form of the solution:

"vmArgs": "--module-path \"enter_the_path_here\" --add-modules javafx.controls,javafx.fxml"

Use this and your code should work perfectly.

I was having the same problem and wasted almost 4 hours solving this. I used this video here: link! as reference. (Caution: the video is in Portuguese)

Try putting everything on one drive other than C. I had my codes in D drive and JavaFX in C, the codes never launched successfully. It didn't work even when I put the codes in the JavaFX folder. However, once I transferred JavaFX files to D drive, it worked.

Check out the samples here: https://github.com/openjfx/samples/tree/master/IDE/VSCode

You can probably use this one, which I guess is the one you are looking for.
