jbpm-work-items: WIH samples have broken dependencies

The project jbpm-work-items (https://github.com/kiegroup/jbpm-work-items) has most of the WIH samples broken/outdated and won't work if deployed in the Kie-Server.

It is possible to compile and generate the jar for the sample custom work items without any error or warning. It is also possible to install them in the Business Central and  consume them from process designer. The project builds and is deployed with no errors. However, there are errors in the "Execution Severs" and in the console.  The issue is being caused because the work item dependencies cannot be solved to properly deploy and initialize the project.

e.g. jabber-workitem

Atual: It is not possible to sucessfully deploy  projects with sample work items from jbpm-work-items  project.

Expected:  It should be possible to sucessfully deploy projects with sample work items from jbpm-work-items  project and exectute them.
