Error message

The requested parent version range '%s' does not specify an upper bound

What it means

UnresolvableModelException from BootstrapModelResolver.resolveModel(Parent): the <parent> version is an open-ended Maven version range without an upper bound. The resolver requires an upper bound to pick the highest matching version, so model resolution is refused outright.

Solutions

1. Add an upper bound to the parent version range, e.g. '[1.0,2.0)'
2. Or replace the range with a concrete parent version
