Cloning parameters of the 'run' task

This seems like something that’s much harder to accomplish than it should be. How do I get a full set of arguments to java that the run task uses? Technically I can copy all properties like so:

project.getTasks().register("runDetached", JavaFork.class, task -> {
    var runTask = (JavaExec) project.getTasks().getByName("run");
    task.setGroup("application");
    task.setDescription("Runs this project as a JVM application in the background");
    task.getMainClass().set(runTask.getMainClass());
    task.getMainModule().set(runTask.getMainModule());
    task.setClasspath(runTask.getClasspath());
    task.getJavaLauncher().set(runTask.getJavaLauncher());
    task.setJvmArgs(runTask.getJvmArgs() != null ? runTask.getJvmArgs() : List.of());
    task.getJvmArguments().set(runTask.getJvmArguments());
});

Then put all of this together in the @TaskAction of my custom task:

var command = new ArrayList<String>(16);
command.add(getJavaLauncher().get().getExecutablePath().toString());
command.addAll(getAllJvmArgs());
command.addAll(getJvmArgs());
if (getMainModule().isPresent()) {
    command.add("--module-path");
    command.add(getClasspath().getAsPath());
    command.add("--module");
    command.add(getMainModule().get() + '/' + getMainClass().get());
} else {
    command.add("-cp");
    command.add(getClasspath().getAsPath());
    command.add(getMainClass().get());
}
command.addAll(getArgs());

But surely there has to be a better way, right? After all, the full command used by run is already logged when running with the --info flag.

I don’t think what you want is achievable without using Gradle internals. Or at least I’m not aware how.
