Problems with Red Hat Central/Spring MVC Project

Hi everybody,
recently i had install Red Hat Developer Sudio on Eclipse (version Neon) and some plugin (ie Spring, Maven ecc.).
In the Project menu creation there is a section named 'Red Hat Central'. Under this section there is a 'Spring Mvc Project'.
I have a Jboss EAP 7.x installed like Server.
When i try to create Spring Project by this menu, there is an error on dependency Maven Artifact, like the snapshot attach. I try to install this dependency but the jar of this feature seems not have a correct xml descriptor to insert in Maven add Repository (local o remote).
Any suggest.
