There are three types of Maven repositories.
They are:
Local Repository: This is placed in our local machine generally in the .m2 directory. This is generated once we are able to execute a Maven command successfully. All the project dependencies reside here. Once Maven scans the pom file, it first searches for its dependencies in the local repository.
Central Repository: This is supplied by Apache Maven. It contains most of the routinely used libraries. Once any of the dependencies are not found in the local repository, then Maven connects to a central repository.
Remote Repository: Sometimes companies develop their own custom repository comprising of their project artifacts, jars, and libraries. This is a type of repository that remains private for use inside that organization.
