org.jbpm.contrib:workitems as a parent pom results in broken version handling

[mP1]

When creating a work item handler using the parent results in broken versioning.

  <parent>
    <groupId>org.jbpm.contrib</groupId>
    <artifactId>workitems</artifactId>
    <version>7.40.0.20200703</version>
  </parent>

It is impossible to actually use your own version numbers because they will break resolution of dependencies within the parent, many of which are missing version numbers of any kind. This makes version management of the actual project completely broken, its not possible to have "different" published versions of the same work-item because they wont build.
