May 19, 2021
<localRepository> element in settings.xml file.
<localRepository>{path-to-local-repo}</localRepository>
<localRepository> is ${user.home}/.m2/repository.
settings.xml
Thesettings.xml file can be found in two locations.
1. ${maven.home}/conf/settings.xml
2. ${user.home}/.m2/settings.xml
The
${maven.home} is Maven installation home and ${user.home} is location of user specific directory. Find the location of settings.xml for ${user.home} OS wise.
1. Windows
C:\Users\<user_name>\.m2
/home/<user_name>/.m2
~/.m2
/Users/<user_name>/.m2
~/.m2
The
settings.xml file located in ${maven.home} is called global setting and settings.xml file located in ${user.home} is called user specific setting. If both file exists, their contents are merged and user specific settings.xml located in ${user.home} will be dominant.
<localRepository>
The location of local repository of a build system are configured using<localRepository> element in settings.xml file.
settings.xml
<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 https://maven.apache.org/xsd/settings-1.0.0.xsd">
<localRepository>${user.home}/.m2/repository</localRepository>
......
</settings>
<localRepository> is ${user.home}/.m2/repository. We can change the location of local repository using <localRepository> element by passing our local repository location.
<localRepository>{path-to-local-repo}</localRepository>
Purging Local Repository Dependencies
Use following command to purge local repository.mvn dependency:purge-local-repository
By default, the plugin operates on all transitive dependencies. Plugin may download the certain missing dependencies to gather the full dependency information before beginning the purge process. We can avoid the pre-download step using following command.
mvn dependency:purge-local-repository -DactTransitively=false
