无法在libgdx项目中启动ipad-iphone模拟器

Question

我正在开发一个libgdx项目。我想将项目部署到android和ios。该项目正在桌面（MacOS），Android模拟器和Android设备上工作。但是，当我尝试使用gradle或main类启动IOS模拟器时，会抛出错误。我还下载了另一个robovm示例。这些项目可以启动具有类似代码的模拟器。

Libgdx IOS主类如下：

public class IOSLauncher extends IOSApplication.Delegate {
@Override
protected IOSApplication createApplication() {
    IOSApplicationConfiguration config = new IOSApplicationConfiguration();
    return new IOSApplication(new DemoProject(), config);
}

public static void main(String[] argv) {
    NSAutoreleasePool pool = new NSAutoreleasePool();
    UIApplication.main(argv, null, IOSLauncher.class);
    pool.close();
}
}

错误如下：

Exception in thread "main" java.lang.UnsatisfiedLinkError: org.robovm.rt.VM.getStackClasses(II)[Ljava/lang/Class;

事实上，我更喜欢使用gradle。

但它抛出的错误如下：

我该怎么办？
