Ionic 上的 Pushwoosh cordova 插件出错

Question

我刚刚在我的 Ionic 项目上安装了Pushwoosh cordova plugin，现在我无法在我的设备上运行该应用进行测试。

这里是官方docs

如果我运行： ionic cordova run android --consolelogs --device --livereload

我明白了：

:compileDebugJavaWithJavac
/media/ivan/SharedPartition/Trabajo/AnimaEdu/animaedu-mobile/platforms/android/src/com/pushwoosh/plugin/pushnotifications/PushNotifications.java:888: error: lambda expressions are not supported in -source 1.6

            mainHandler.post(() -> webView.loadUrl("javascript:"+ url));
                                ^
  (use -source 8 or higher to enable lambda expressions)
1 error

我不明白输出。

有什么想法吗？提前致谢！

Answer 1

问题很简单：

错误原因 --> -source 1.6 不支持 lambda 表达式

您正在使用JDK 1.6，而此插件的代码需要在JDK 1.8 或更高版本上编译。
