Maven repositories

local repositories

-in maven Home Directory >conf >setting.xml

-then we will find <local repo>there keep the path </local repo>

It is a local folder that is used to store all the project dependencies(plugin jars and other files that are downloaded by Maven)
- when you build a Maven project all dependency files will be stored in the Maven local repository

- default maven local repository defaults to .m2 folder

-mac os > ~/.m2 (/users/Suma/.m2/repository)

-Windows > c:\users\Suma\.m2\repository

-Linux > /home/Suma/.m2/repository

central repositories

the repo provides by the maven community. It contains a large repository of commonly used libraries.
- this repo comes into play when Maven does not find libraries in the local repo
- the central repo can be found at https://maven.apache.org/
Remote repositories

It usually maintains its repo for the libraries that are being used for the project. These differ from the local repo, a repo is maintained on a separate server different from the developer machine and is accessible within the organization
