A Guide to Maven Repositories and Artifact Management

APACHE MAVEN



Maven repositories are central locations where Maven can find and download project dependencies, plugins, and other artifacts.

There are two types of repositories in Maven: local repositories and remote repositories.


1. Local Repository: The local repository is a cache on the developer's machine that stores all the dependencies that have been downloaded for a particular project. 

The local repository is located in the `.m2` directory in the user's home directory.


2. Remote Repository: The remote repository is a repository that is hosted on a remote server and contains artifacts that are not available in the local repository.

Maven can download dependencies from remote repositories, such as the Maven Central Repository or a custom repository.

When Maven needs to download a dependency or artifact, it first looks in the local repository. If the artifact is not found in the local repository,

Maven looks in the configured remote repositories. If the artifact is still not found, Maven will fail with an error.


Maven also allows developers to define their own custom repositories. These repositories can be hosted on a remote server or on the local machine. 

Custom repositories can be used to store private or proprietary artifacts that are not available in public repositories, or to proxy remote repositories to improve performance and reliability.
