I tried to install a plugin from a GitHub repo with the following line in my config.xml: <plugin name="cordova-plugin-extra-events" spec="https://github.com/distinctdan/cordova-plugin-extra-events.git" /> but I receive the following error: UserError: Error: Plugin 'cordova-plugin-extra-events' is not listed in https://npmjs.com.
Is it possible to install plugin from other sources apart from npm? Especially GitHub.
