dependencyManagement and scope

As with other answers, best practice is to exclude scope from dependencyManagement and explicitly specify it when defining the dependency. It is a rare case that you would want a different version of the same dependency in different scopes, e.g., one version when compiling your app and a different when running it -- the only case I can think of is you want to explicitly run your tests against a different version of a library in case users use that version instead of the one you specify.

If you define scope in dependencyManagement, it restricts the use of that version to ONLY the defined scope -- so any other scopes will pick up a random version of the dependency. I ran into this yesterday when we had defined junit 4.12 in dependencyManagement with test scope, but our common test framework module used junit with compile scope, so it picked up version 4.8.2 instead.
