我正在使用LibGDX构建游戏，我正在尝试将Facebook登录功能添加到iOS项目中。我正在使用RoboVM编写特定于平台的代码。但是，在使用Gradle构建iOS项目时，我从堆栈跟踪中看到了这个错误：
./gradlew launcIPhoneSimulator --stacktrace
Configuration on demand is an incubating feature.

此处还有iOS项目的Gradle脚本：

我还将FBSDKLoginKit添加到我的robovm.xml文件中，但问题仍然存在。 任何帮助都会很棒。 提前谢谢！
答案 0 :(得分：1)
好的，我在Mario Zechner的帮助下解决了这个问题。 正如他在此所述https://groups.google.com/forum/#!topic/robovm/Ume9XVrGQBg 更新到RoboVM版本1.14.0并删除〜/ .robovm文件夹解决了问题！
