Maven - Introduction to the Dependency Mechanism

Differences between dependencymanagement and dependencies in maven

The dependency management section is a mechanism for centralizing dependency information. When you have a set of projects that inherits a common parent it's possible to put all information about the dependency in the common POM and have simpler references to the artifacts in the child POMs.



It can used to pull all the dependency information into a common POM file, simplifying the references in the child POM file.

It becomes useful when you have multiple attributes that you don't want to retype in under multiple children projects.
