我创建了一个非常基本的JavaFX应用程序

// Viewer.java
package crossjavafx;

public class Viewer {
    public static void main(String[] args) {
        MainViewer.main(args);
    }
}

// MainViewer.java
package crossjavafx;

import javafx.application.Application;
import javafx.scene.Group;
import javafx.scene.Scene;
import javafx.stage.Stage;

public class MainViewer extends Application {

    @Override
    public void start(Stage stage) {
        try {
            System.out.println("Hello from Viewer");
            Group root = new Group();
            Scene scene = new Scene(root,400,300);
            stage.setTitle("Hello");
            stage.setScene(scene);
            stage.show();
        } catch (final Exception e) {
            system.exit(1);
        }
    }

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

还有简单的pom.xml

我已经使用mvn和在Ubuntu 16.04上构建了它：

 ./java -version
openjdk version "1.8.0_222"
OpenJDK Runtime Environment (build 1.8.0_222-8u222-b10-1ubuntu1~16.04.1-b10)
OpenJDK 64-Bit Server VM (build 25.222-b10,mixed mode)

我还安装了openjfx和libopenjfx软件包：

libopenjfx-java/xenial,xenial,now 8u60-b27-4 all [installed]
libopenjfx-jni/xenial,now 8u60-b27-4 amd64 [installed,automatic]
openjfx/xenial,now 8u60-b27-4 amd64 [installed]

该应用程序已成功构建，但无法启动。在打印“来自Viewer的Hello”之前，该过程挂起。我开始了：

/usr/lib/jvm/java-8-openjdk-amd64/bin/java -cp crossjavafx-0.1.0-snAPSHOT.jar crossjavafx.Viewer

即使从相同的JAR调用其类，我也可以用相同的方式启动非javafx应用程序构建，因此，我想我的JavaFX安装有问题。

我还尝试构建它并使用Java 8 Oracle SDK运行，结果相同。我的JavaFX安装中遗忘了什么吗？

修改

我已经构建并尝试使用Java 8 Oracle运行它，并打印stacktrace。我得到了：

Hello from Viewer
