Both demo plugins are currently build as JAR files in the same way. To make it easier for new users and to better document the features of PF4J it might make sense, if one of the plugins is created as ZIP file (including a 3rd party library in the lib folder).

Because I'm always using ZIP plugins in my project and already have a working Maven configuration for this, I would provide a pull request, that changes the build process of the 2nd demo plugin in order to create a ZIP archive.

This would make it easier for new users to use one of the demo plugins as an example for their own project. We also might point from the packaging page of the documentation to both example plugins.

Let me know, what you think about this and if I can provide a pull request for this.
