I think you misunderstood. The dependencyManagement is used for
project dependencies, fine with that.
When you use a plugin no dependencyManagement is applied. The current
project depMan shouldn't be applied because it's only for projects, so
that's ok.
The problem comes when a plugin is built using dependencyManagement to
force some dependencies. When that plugin is used, the
dependencyManagement of the plugin is ignored, so you run it with
different dependencies than the ones you build it with.
