You don't have to define the version multiple times. If you've specified it in dependencyManagement, you don't have to add a <version> under <dependencies>. If you do it in the parent POM, you won't have to specify versions in the child POMs either. The only time you have to repeat the versions of dependencies is when there are related dependencies that should be the same version. E.g. dependencies with separate packages for modules, like Jackson or Spring. And if the dependency has a BOM pom, that's not needed either.
