What are different repository types in Maven ?

Maven repo

• A directory of JAR file with pom.xml file
• used to search the dependencies
• Order of searching dependencies : Local -> Central -> Remote

1. Local

• in local system (Default : %USER_HOME%/.m2 directory)
• To change location : MAVEN_HOME/conf/settings.xml
• Directory automatically created when you run any maven command

Change location of local repo in settings.xml
<settings>
  <localRepository>/path</localRepository> 
</settings>


2. Central

• Repo created by Maven on internet (Location : http://repo1.maven.org/maven2/)
• contains common libraries

3. Remote

• Available on internet
• Some libraries which are not available on Central repo , they can be found in Remote repo
• Libraries (to use from Remote repo) are specified in pom.xml
