Make executable jar with JavaFx plugin for gradle - javafx

Question

I'm trying to make an executable jar.
My IDE is Netbeans 7.3.1, using Gradle plugin for Netabeans, using JavaFX plugin for Gradle.
Simple JavaFX application:
i.lunin.autoposting.Main:
package i.lunin.autoposting;
import java.util.logging.Level;
import java.util.logging.Logger;
import javafx.application.Application;
import javafx.event.ActionEvent;
import javafx.event.EventHandler;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.layout.StackPane;
import javafx.stage.Stage;
public class Main extends Application {
public static void main(String[] args) {
launch(args);
}
#Override
public void start(Stage primaryStage) {
primaryStage.setTitle("Hello World! Man!");
Button btn = new Button();
btn.setText("Say 'Hello World'");
btn.setOnAction(new EventHandler<ActionEvent>() {
#Override
public void handle(ActionEvent event) {
try {
Thread.sleep(5000);
} catch (InterruptedException ex) {
Logger.getLogger(Main.class.getName()).log(Level.SEVERE, null, ex);
}
System.out.println("Hello World!");
}
});
StackPane root = new StackPane();
root.getChildren().add(btn);
primaryStage.setScene(new Scene(root, 300, 250));
primaryStage.show();
}
}
Gradle file:
build.gradle:
apply from: "http://dl.bintray.com/content/shemnon/javafx-gradle/0.3.0/javafx.plugin"
apply plugin: 'java'
sourceCompatibility = '1.7'
[compileJava, compileTestJava]*.options*.encoding = 'UTF-8'
repositories {
mavenCentral()
}
dependencies {
}
group = 'i.lunin.autoposting'
version = '0.0.0'
javafx {
mainClass = 'i.lunin.autoposting.Main'
}
When I use gradle run, it runs perfectly inside my IDE; But I can't start it without IDE.
When I use gradle :jfxDeploy It says that the is finished.
After that, when I'm try to start the executable jar from:
"... TestJava\build\distributions"
It shows the following error: "Unable to find class: i.lunin.autoposting.Main"
Please help me make an executable jar under netbeans, gradle.

Answer 1

I recently had the same issue. For me it turned out to be the build system.
If I build my app via gradle and javafx on a 32bit jvm, it resulted in the same error you had.
If I built it on a 64bit system everything went fine.
So I guess it's still a problem to deploy self contained 32bit java apps. I tested it with Java 7.

There seems to exist a newer plugin which looks very promissing:
From the repository README:
Using javafx-gradle-plugin enhances your build-script with
javapackager-power. No more using Apache Ant-calls, because this
gradle-plugin wraps all calls and introduces workarounds and fixes for
not-yet-fixed JDK-bugs. This gradle-plugin is a convenient-wrapper for
the javapackger, so you have to visit the official documentation to
know about the requirements on each operating-system.
Why does this gradle-plugin exist?
In the need of some equivalent of the javafx-maven-plugin just for
gradle, this project was born. A lot of you might have used the
javafx-gradle-plugin from Danno Ferrin, but he decided to not continue
that project.
