How to setup/configure IntelliJ IDEA with JavaFX and Java 11-14?

With Java 11, JavaFX libraries were excluded from the JDK library, so to use JavaFX you need to download and manually attach the missing libraries to the project.

JavaFX download

To download the JavaFX package, go to and select the appropriate version for us. In my case it will be “JavaFX Linux SDK”.

The downloaded package should be unpacked. We will be adding these libraries to the project in the next steps.

Setup JDK

In IntelliJ go to File -> Project Structure -> Project, and then set the appropriate JDK version.

In the Modules tab, we also set the correct JDK.

Adding JavaFX library

Then go to File -> Project Structure -> Libraries and add New Project Library by clicking the plus button +. Select the lib folder in the directory where we previously unpacked the JavaFX SDK library.

(We can also define this library as Global Libraries, and then only import to individual projects / modules).

Launching the application

If you get an error when starting the application:

Error: JavaFX runtime components are missing, and are required to run this application

then you need to add the module in the VM options (remember to change the path).


--module-path /home/pawel/Desktop/javafx-sdk-11.0.2/lib --add-modules javafx.controls,javafx.fxml


--module-path "C:\javafx-sdk-11.0.2/lib" --add-modules javafx.controls,javafx.fxml

It’s all! Run the app and see it works! 🙂
