We observed several times that Eclipse freezes when enabling the maven dependency manager for the first time. If this happens, we suggest the following: (i) kill Eclipse (ii) start Eclipse again (iii) disable maven dependency management (right click on project, Maven > Disable Dependency Management) (iv) enable maven dependency management again. In the second try, things usually work.
