Maven Local Repository is a feature provided in Maven that allows you to manage local copies of your project’s dependencies. By default, Maven makes a copy of each dependency artifact that is used in your project and stores it in the local repository.

Customize Maven Local Repository
The settings.xml is the main configuration file of Maven. It is available for user-level or system-level configurations.
- Global level: Is available at
${MAVEN_HOME}/conf/settings.xmlis applied for all Maven users on the system that share the same installation. - User level: Can be found at
${HOME}/.m2/settings.xml. This is the user-specific configuration and overrides the global configuration.
To customize the local repository, edit settings.xml and change directory location with <localRepository> tag.
1 2 3 4 5 | <settings xmlns="http://maven.apache.org/SETTINGS/1.2.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.2.0 https://maven.apache.org/xsd/settings-1.2.0.xsd"> <localRepository>/opt/maven_local_repo</localRepository> |

mvn -Dmaven.repo.local=/opt/maven_local_repository install
