在我安装、配置好PhoneGap项目的所有依赖后，试图执行
$ cordova run android
命令时，出现过如下错误。
Error: /home/sam/front/redwine/platforms/android/cordova/run: Command failed with exit code 8

cordova build android或cordova emulate android的结果也是一样。
但其实真正的问题在上面几行：
[aapt] (skipping file '.jshintrc' due to ANDROID_AAPT_IGNORE pattern '.*')
[aapt] (skipping file '.bower.json' due to ANDROID_AAPT_IGNORE pattern '.*')
[aapt] (skipping file '.directory' due to ANDROID_AAPT_IGNORE pattern '.*')

这是因为项目下有多个node_modules目录，被重复打包而引发的Command failed with exit code 8问题。
解决办法是修改platforms/android/build.xml：
<property name="aapt.ignore.assets" value="<dir>node_*" />
将node_modules目录排除掉，就可以正常执行cordova命令。
