android的crosswalk项目构建失败

我正在尝试使用Crosswalk构建android应用程序。我按照这个来设置。 建设成功。但当我试图从自己的HTML5项目中构建时，它构建失败了

错误输出：

这是我的环境设置：

export ANT_HOME=/home/jian/app/ant

这是版本信息：

java -version

Apache Ant(TM) version 1.9.6 compiled on June 29 2015

adb help

这是发生错误的ant/build.xml的一部分

为什么我成功地构建了示例项目，但未能构建自己的项目？我该如何修复这个错误。谢谢你的帮助

您可以向报告您的问题，以获得Crosswalk developer更快的响应。

我也遇到了同样的问题

我降级了Java版本以修复它：

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)

你最终找到解决办法了吗？不幸的是我没有找到原因
