【问题描述】：
我正在做一些与这个问题相关的研究：Phonegap plugin result when app is not active anymore
所以，我已经 fork https://github.com/MobileChromeApps/mobile-chrome-apps 并根据 https://github.com/MobileChromeApps/mobile-chrome-apps/blob/master/dev-docs/release-instructions.md 构建了自己的版本，以便使用 gcm 与几天后添加但尚未发布的移动 chrome 应用程序的兼容性npm。
但是，当运行cca build 时，GCM 插件似乎运行得不太好：

我对 Java 真的很不放心。而且我不知道该怎么办。
