  property is not inherited from a POM to its child: child's POM will use child artifact id if property is not
  set.

  ** since Maven 3.6.1, inheritance can avoid appending any path to parent value by setting model attribute value to
  <<<false>>> for each url:
  <<<project/@child.project.url.inherit.append.path>>>,
  <<<project/distributionManagement/site/@child.site.url.inherit.append.path>>>,
