JavaFX with ForgeGradle

[DerTod2]

Hi,

 

Is it possible to compile Mods using JavaFX (using jdk 1.8.0) with ForgeGradle? Currently the build throws "unknown package"

Can I add additional dependencies anywhere?

Java 8 causes problems with ForgeGradle. Downgrade to 7u55.

[GotoLink]

You can add dependencies in the build.gradle file, using remote maven or local jar.

[DerTod2]

Well now ForgeGradle compiles succesfully with these lines in the gradle.build:

 

dependencies {
  compile files("C:/Program Files/Java/jdk1.8.0_05/jre/lib/ext/jfxrt.jar")
}

 

The next problem (maybe an java problem?) is the NoClassDefFound Exception when running the mod and starting to play an youtube video. Java throws this exception:

Eclipse throws no warnings and the lib should be in every Oracle Java Installation. Then why is the class "javafx.scene.Parent" missing ...

 

The java File containing the JavaFX imports looks like this:

 

 

 

package net.dertod2.UnitedMC.Classes;

import java.io.File;

import javafx.scene.Scene;
import javafx.scene.web.WebView;
import javafx.stage.Stage;
import javafx.stage.StageStyle;

public class YoutubePlayer extends PlayerWrapper {
private Stage stage;
private WebView webView;

protected YoutubePlayer(MusicTitle musicTitle, long timeDifference, long startedAt) {
	super(musicTitle, timeDifference, startedAt);

	this.stage = new Stage(StageStyle.TRANSPARENT);
	this.webView = new WebView();
}

@Override
public void stop() {
	this.webView.getEngine().load("http://localhost"); // Force load simple document
}

@Override
public boolean play(File file) {
	this.webView.getEngine().load(this.getTitle().getPath() + "?autoplay=1&t=" + this.getStartTime());

	this.webView.setPrefSize(1, 1);
	this.stage.setScene(new Scene(this.webView));
	this.stage.show();

	return true;
}

private String getStartTime() {
	long differenceMilliseconds = ((System.currentTimeMillis() - this.getStarted()) + this.getDifference());
	return (differenceMilliseconds / 1000) + "s";
}

public long getSongLength() {
	// TODO Auto-generated method stub
	return 0;
}

public boolean isPlaying() {
	return false; // TODO
}

public long getProgress() {
	return 0;
}

public void setVolume(float volume) {
	// TODO Auto-generated method stub

}

}

 

The problematic line should be "this.stage.setScene(new Scene(this.webView));"

 

 

 

Thanks for the Help!
