在命令行界面中使用Java模块设置运行9+

Question

操作系统: Linux Mint18.3我想运行的组合是: Groovy 3.0.+ (应用程序和测试代码)& Java 11+ & JavaFX 11+

有了一点帮助(参见注释here)，我现在可以使用gradle.build文件(包括使用application插件中的Gradle "installDist“任务输出可执行文件)。

我还在IntelliJ中的一个未启用Gradle Groovy的项目中实现了这一点，方法是适当地配置类路径和模块路径。

我的文件javaFXTest.groovy看起来像这样(注意，这是我让IntelliJ运行的Groovy脚本)：

package core

import javafx.application.Application
import javafx.fxml.FXMLLoader
import javafx.scene.Parent
import javafx.scene.Scene
import javafx.stage.Stage

Application.launch(  GrApp, args)

class GrApp extends Application {

    @Override
    void start(Stage primaryStage) {
        Parent root = FXMLLoader.load(getClass().getResource("/dialog1.fxml"))       
        primaryStage.title = "Hello World"
        primaryStage.scene = new Scene(root, 1200, 800)
        primaryStage.show()
    }
}

出于兴趣，我只是想知道，在命令行界面groovy命令中，这实际上是如何完成的。我想可能是这样的：

groovy -cp .:/home/mike/.java/JavaFX/javafx-sdk-11.0.2/lib/*  --module-path /home/mike/.java/JavaFX/javafx-sdk-11.0.2/lib --add-modules javafx.controls,javafx.fxml core/javaFXTest.groovy 

糟了：

Caught: java.io.FileNotFoundException: /home/mike/IdeaProjects/JavaFXExp2/AppTest/src/main/groovy/--module-path (/home/mike/IdeaProjects/JavaFXExp2/AppTest/src/main/groovy/--module-path)

..。它显然不承认--module-path是一个可配置的选项，这一点在groovy --help中得到了确认。我在这上面搜索了一下，什么也没找到。然而，IntelliJ设法运行这个脚本：--module-path和--add-modules选项作为VM选项添加到运行配置中。有人知道这是如何作为CLI命令来完成的吗？

根据cfrick的建议，我找到了答案: Intellij确实在"Run“视图中显示了整个命令(如果您单击”...“)：

事实证明，这是一个巨大的Java命令，其中包含了我无法理解的各种内容，例如，包含了许多Groovy .jars。我为所有感兴趣的人展示了它的壮丽:我将其分成几行，以便更清楚地显示选项。

我大胆地猜测，第一个-classpath选项(带有单个破折号)可能是为“javaagent”设置的……或者可能是"Groovy starter“？

这至少解决了一个难题:我知道Groovy (甚至Groovy3)不能处理Java 9+模块。因此，这必须是一个Java命令是有意义的。也许Groovy4可以运行groovy命令，据我所知，Groovy4将(希望)能够处理这些模块。
