Cordova-plugin-crosswalk-webview folder is empty


#1

I see https://crosswalk-project.org/documentation/cordova_4.html.
6th step ,cordova build android,
It did not automatically fetch the stable Crosswalk WebView libraries,why?
I have been using cordova 4 ,
ionic browser add crosswalk is fine.
Cordova 5 ’s Changed.
