javafx support?

[bk322]

I open java file

https://github.com/openjfx/samples/blob/master/IDE/Eclipse/Non-Modular/Maven/hellofx/src/main/java/org/openjfx/hellofx/MainApp.java

and as soon as I save it -- eclipse.jdt.ls changes

import javafx.stage.Stage;

to

import org.graalvm.compiler.phases.common.NodeCounterPhase.Stage;

After this project won't compile.

What should I do to make it work?

Looks like I forget to do something on importing the project, like caching the pom.xml dependencies. If that so how do I force eclipse.jdt.ls to cache pom.xml dependencies?
