I tried to include the "es6-promise-plugin" in two different ways:
I tried to fork the Social Sharing plugin on my own GitHub and edit this line in the "plugin.xml" file:
<dependency id="es6-promise-plugin" url="https://github.com/vstirbu/PromisesPlugin.git"/>
and then I included my Git instead of Eddy Verbruggen's in the Build parameters.
I also tried to let Eddy Verbruggen's Git in the Build parameters and before it I also included "es6-promise-plugin" like so:
In both cases the build fails with the following log:
Adding plugin from: https://github.com/EddyVerbruggen/SocialSharing-PhoneGap-Plugin.git
Does not appear to be an xcode project, no xcode project file in STAGING/client/modules/AGCordova
