JavaFxPorts on iOS with Gluon

问题:

i am using a MacBook Pro with OS X El Capitan Version 10.11.3. I try to start a simple "Hello World" Project from Gluon/javaFXports with the iOS Simulator.

If i simply run the project it works on my desktop but every time i run it with "launchIPhoneSimulator" this happens:

14:52:46: Executing external task 'launchIPhoneSimulator'...
:compileJava UP-TO-DATE
:compileRetrolambdaMain UP-TO-DATE
:processResources UP-TO-DATE
:classes UP-TO-DATE
:createDefaultIOSLauncher UP-TO-DATE
:compileIosJava UP-TO-DATE
:processIosResources UP-TO-DATE
:iosClasses UP-TO-DATE
:launchIPhoneSimulator FAILED

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':launchIPhoneSimulator'.
> Unable to find a matching device [arch=x86, family=iPhone, name=null, sdk=null]

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

BUILD FAILED

Total time: 1.986 secs
Unable to find a matching device [arch=x86, family=iPhone, name=null, sdk=null]

I am a developer for Apple, but i just got the free account maybe thats the problem?

I have no other idea. Can you help me please?

Check that you have XCode installed and updated. You should open it at least once and accept the license. Also you can check XCode -> Window -> Devices for the list of simulators.

This is what I see when I run ./gradlew --info launchIPhoneSimulator:

ios simulator os ios
ios simulator target org.robovm.compiler.target.ios.IOSTarget@3c833d1a
ios simulator arch x86
ios simulator device type DeviceType [deviceName=com.apple.CoreSimulator.SimDeviceType.iPhone-6, 
    sdk=SDK 
    [displayName=Simulator - iOS 9.2, 
    minimalDisplayName=Simulator - 9.2, 
    canonicalName=iphonesimulator9.2, 
    version=9.2, 
    root=/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator9.2.sdk, 

    major=9, minor=2, revision=0, build=13C75, platformBuild=13C75, platformVersion=9.2, platformName=iphonesimulator], 
    archs=[x86_64, x86]]

According to this, you can try to find out which devices and SDKs you have:

To get a list of possible device names and matching sdk versions, you can run the command ios-sim showdevicetypes. As well, you can run iso-sim showsdks to find out about the supported sdk versions.

the ios-sim command can be found in your local maven repository (which by default is located in your user home directory .m2/repository) under org/robovm/robovm-dist/ROBOVM_VERSION/unpacked/robovm-ROBOVM_VERSION/bin (replace ROBOVM_VERSION with the version used by the jfxmobile plugin).

You should use also the latest version of the plugin (check your build.gradle file):

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'org.javafxports:jfxmobile-plugin:1.0.7'
    }
}

This version makes use of the RoboVM 1.8.0.
