参考：https://stackoverflow.com/questions/36654990/error-building-xwalk-with-cordova-android

Here's the quote from the post:

"This can solve the issue for latest crosswalk version.

Open platforms\android\cordova-plugin-crosswalk-webview\eqp-xwalk.gradle

change this:

dependencies {
    xwalkSpec
}

to this one:

dependencies {
   compile 'org.xwalk:xwalk_core_library:23.53.589.4' //xwalkSpec
}
