我正在尝试使用人行横道构建android应用程序。我按照这个官方指南来设置。并成功构建了实例工程。但是当我尝试从我自己的HTML5项目中构建时，它构建失败了。
错误输出:

为什么我成功地构建了示例项目，但未能构建自己的项目?如何修正这个错误。谢谢你的帮助!
我也遇到过同样的问题。
我降级Java版本来修复它:
java -version
java version "1.7.0_51"
Java(TM) SE Runtime Environment (build 1.7.0_51-b13)
Java HotSpot(TM) 64-Bit Server VM (build 24.51-b03, mixed mode)
