A repository manager is a dedicated server application designed to manage
repositories of binary components.
The usage of a repository manager is
considered an essential best practice for any significant usage of Maven.
Purpose
A repository manager serves these essential purposes:


act as dedicated proxy server for public Maven repositories
(see Maven Guide to Mirror Settings)
provide repositories as a deployment destination for your Maven project
outputs

Benefits and Features
Using a repository manager provides the following benefits and features:


significantly reduced number of downloads off remote repositories, saving time
and bandwidth resulting in increased build performance
improved build stability due to reduced reliance on external repositories
increased performance for interaction with remote SNAPSHOT repositories
potential for control of consumed and provided artifacts
creates a central storage and access to artifacts and meta data about them
exposing build outputs to consumer such as other projects and developers, but
also QA or operations teams or even customers
provides an effective platform for exchanging binary artifacts within
your organization and beyond without the need for building artifact from source
