Building JavaFX applications

[Ekaitz Zarraga]

Hi,

I need help building javafx applications. I don't know how to build a simple 
app:

This is my environment:

```
Ekaitz@tuxedo ~/projects/window$$ guix shell openjdk openjdk:jdk 
java-openjfx-graphics java-openjfx-controls java-openjfx-media 
java-openjfx-base java-openjfx-build
```

I look for the javafx module paths:

```
Ekaitz@tuxedo ~/projects/window$ [env]$ guix build java-openjfx-graphics 
java-openjfx-controls java-openjfx-media java-openjfx-base java-openjfx-build
/gnu/store/rynjd6sbgqhz7zpgzrdzl8fcpbykwxri-java-openjfx-build-8.202
/gnu/store/13l0qiwy3z88hiq49g9zdpcj77i16fx9-java-openjfx-base-8.202
/gnu/store/bwpkcbcm8cwkdcq7sviyya6pjb4ma3zk-java-openjfx-media-8.202
/gnu/store/f4bbx3524avpw1yn9b0z0fax9rmx4ayd-java-openjfx-controls-8.202
/gnu/store/hpcja76y3y0hpgkxvmv68jhxjlny2316-java-openjfx-graphics-8.202
```

If I don't add them to module paths they don't appear:

```

But I can't compile a file with them:

```

```

This is the file I'm trying to compile:

``` java
import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.Label;
import javafx.scene.layout.StackPane;
import javafx.stage.Stage;

public class HelloFX extends Application {

    @Override
    public void start(Stage stage) {
        String javaVersion = System.getProperty("java.version");
        String javafxVersion = System.getProperty("javafx.version");
        Label l = new Label("Hello, JavaFX " + javafxVersion + ", running on 
Java " + javaVersion + ".");
        Scene scene = new Scene(new StackPane(l), 640, 480);
        stage.setScene(scene);
        stage.show();
    }

    public static void main(String[] args) {
        launch();
    }

}
```

Can anyone help me solve this issue?

Is it possible to simple add them via the CLASSPATH and avoid the module system?

Thank you!
