Download an appropriate JavaFX runtime for your operating system and unzip it to a desired location. For this tutorial, we will be using JavaFX .

Add an environment variable pointing to the lib directory of the runtime: (e.g. you have download and unziped "javafx-sdk-11.0.2")

set PATH_TO_FX="C:\Program Files\javafx-sdk-11.0.2\lib"

You can now compile and run JavaFX applications from the command line using the JavaFX runtime.

Compile the application (e.g. use HelloFX.java from this sample) using:

javac --module-path %PATH_TO_FX% --add-modules javafx.controls HelloFX.java

Run the application (e.g. use HelloFX.java from this sample) using:

java --module-path %PATH_TO_FX% --add-modules javafx.controls HelloFX
