javafx support?

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?

JDT fails to import the project and then returns wrong organize imports actions. I believe it is related to #871

@yyoncho could you try to use Java 11?

did you open the folder or just the file?

I open a java file, emacs asks wither to import hellofx folder, I agree to that.

Emacs has two package that LSP/Eclipse server (lsp-mode, eglot)

I did not know about eglot. I was using lsp/eclipse.

Did you first open a issue at your LSP Emacs package page ?

I just did it, https://github.com/emacs-lsp/lsp-java/issues/82
