异常构建 gradle 任务启动IosDevice答案

【问题标题】：Exception building gradle task launchIosDevice异常构建 gradle 任务启动IosDevice
【发布时间】：2017-04-01 10:11:52
【问题描述】：

在我更新了新版本的 Ios 之后（我认为在这件事之前还可以），当我尝试启动 Gradle 任务“launchIosDevice”时出现这个异常：

java.lang.NullPointerException
        at org.robovm.libimobiledevice.Callbacks.callInstproxyCallback(Callbacks.java:66)

谁能帮我理解这个问题？提前谢谢你。

【问题讨论】：

您在使用 jfxmobile 插件吗？你可以发布你的 build.gradle 吗？运行./gradlew --info launchIosDevice 并发布更详细的堆栈跟踪？另外，./gradew createIpa 对你有用吗？
是的，我正在使用 jfxmobileplugin，我发布了 stacktrace 和 build.gradle 的最后几行。 createIpa 任务正常工作。

【解决方案1】：

将我的 iPad 更新到 iOS 10.3 后，我可以重现运行 ./gradlew --info launchIOSDevice 的错误：

新的 iOS 版本出现了一些问题，这需要 Mobidevelop（Robovm 分支）修复。一旦他们解决了这个问题，就需要一个新版本的 jfxmobile 插件。

已经创建了一个issue，但也许你也可以发布你的。

与此同时，解决方法是在构建 ipa 后手动安装应用程序：

运行./gradlew createIpa，找到/build/javafxports/ios下的ipa，双击它，它会用iTunes打开。然后它将被下载并安装在您的 iOS 设备上。
