JavaFX11:使用Gradle创建jar文件
我正在尝试将JavaFX项目从8Java版本升级到11版本。当我使用“run”Gradle任务()时,它可以工作,但是当我构建(使用“jar”Gradle任务)并执行(使用“java-jar”)一个jar文件时,会出现消息“Error:JavaFX运行时组件丢失,并且需要运行此应用程序” 这是我的build.gradle文件:JavaFX11:使用Gradle创建jar文件,gradle,jar,java-11,javafx-11,Gradle,Jar,Java 11,Javafx 11,我正在尝试将JavaFX项目从8Java版本升级到11版本。当我使用“run”Gradle任务()时,它可以工作,但是当我构建(使用“jar”Gradle任务)并执行(使用“java-jar”)一个jar文件时,会出现消息“Error:JavaFX运行时组件丢失,并且需要运行此应用程序” 这是我的build.gradle文件: group 'Project' version '1.0' apply plugin: 'java' sourceCompatibility = 1.11 reposi

你知道我应该怎么做吗?使用Java/javafx11,shadow/fat jar将无法工作 正如你所看到的: 此错误来自java.base模块中的
sun.launcher.launchelper
。原因是主应用程序扩展了应用程序
,并且有一个Main方法。如果是这种情况,LaunchHelper
将检查javafx.graphics模块是否作为命名模块出现:
这意味着,毕竟,您必须安装JavaFXSDK(每个平台)来运行使用maven central的JavaFX依赖项的jar
作为替代方案,您可以尝试使用jlink
创建轻量级JRE,但您的应用程序需要模块化
您还可以使用Javapackager为每个平台生成安装程序。请参阅,这将为Java12生成一个打包程序
最后,还有一个与Java 11/JavaFX 11一起使用的Javapackager的实验版本:
编辑
由于Java启动器会检查主类是否扩展了javafx.application.application
,并且在这种情况下,它需要javafx运行时作为模块(而不是jar)提供,因此一个可行的解决方法是添加一个新的主类,该类将成为项目的主类,该类将调用JavaFX应用程序类
如果您有一个带有应用程序类的javafx11
包:
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), 400, 300);
stage.setScene(scene);
stage.show();
}
public static void main(String[] args) {
launch(args);
}
}
然后您必须将此类添加到该包中:
public class Main {
public static void main(String[] args) {
HelloFX.main(args);
}
}
在构建文件中:
mainClassName='javafx11.Main'
jar {
manifest {
attributes 'Main-Class': 'javafx11.Main'
}
from {
configurations.compile.collect { it.isDirectory() ? it : zipTree(it) }
}
}
现在您可以运行:
./gradlew run
或
最终的目标是将JavaFX模块作为模块路径上的命名模块,这看起来是一个测试应用程序的快速/难看的解决方案。对于发行版,我仍然建议使用上述解决方案。对于Java/JavaFX11,shadow/fat jar将无法工作 正如你所看到的: 此错误来自java.base模块中的

使用最新版本的JavaFX,您可以使用两个Gradle插件轻松分发项目(javafxplugin和jlink) 使用这些插件,您可以:
- 创建一个包含所有所需jar文件的可分发zip文件:它需要执行JRE(使用bash或批处理脚本)
- 使用Jlink为给定操作系统创建本机应用程序:执行该应用程序不需要JRE,因为Jlink在分发文件夹中包含一个“轻”JRE(仅包括所需的java模块和依赖项)
如果你想要一个例子,我就做了。对于最新版本的JavaFX,你可以使用两个Gradle插件轻松分发你的项目(javafxplugin和jlink) 使用这些插件,您可以:
