Maven dependencies are not found, but are locally there


I’m trying to set up a basic maven config for vaadin 7, and use the MVVM bambi addon. mvn install works as long as I exclude the addon.
But when I try to compile it with the addon:
"Could not resolve dependencies for project … " with a list of all vaadin jars.

My Maven config can’t be that wrong, as the dependencies can be found manually in .m2 and execute without the addon.

But what might be wrong then?
