A modern programming language that makes developers happier.

Does someone know how to solve this problem?

```e: Supertypes of the following classes cannot be resolved. Please make sure you have the required dependencies in the classpath:
    class tornadofx.UIComponent, unresolved supertypes: javafx.event.EventTarget
    class <http://tornadofx.App|tornadofx.App>, unresolved supertypes: javafx.application.Application```
For now I’d prefer to rely on Java 8 (because of some other modules of mine), my current Java configuration is:

```openjdk version "1.8.0_232"
OpenJDK Runtime Environment (Zulu 8.42.0.23-CA-macosx) (build 1.8.0_232-b18)
OpenJDK 64-Bit Server VM (Zulu 8.42.0.23-CA-macosx) (build 25.232-b18, mixed mode)```

I think the OpenJDK doesn't include JavaFX, but I might be wrong about this ... I'm still using oracle's JDK [shame on me]

one needs to install openjfx in basic openjdk. But some Azul builds do include it.

Thanks :smiley: , Indeed it was related with the JavaFX. OpenJDK wasn’t including it anymore, now I’m using Zulu with FX.
