Sample connected system plugin

Certified Lead Developer

While creating a sample plug in for connected system if you are following the instructions and using the code snippet provided in the - reference docs, may get below errors while deploying the plugin.

Failed to retrieve input stream from plugin descriptor file: appian-plugin.xml

and below some lines in the log it says

AppianOsgiPluginFactory.reportUnloadablePlugin [*/appian/_admin/plugins/hello-appian-csp-1.0.jar]
java.lang.IllegalArgumentException: The validated string is empty

There is a problem with the plugin.xml example snippet in the reference page. 
instead of appian-plugin it mentions appian-plug-in and instead of plugin-info it mentions plug-in-info.
