Maven

Repository

• In Maven we have three repositories
  • Local Repository (~/.m2/repository)
  • Remote Repository: Present with in organizational boundary where we can download dependencies and store artifacts. Jfrog and Nexus can be used as Remote Repositories
  • Central Repo: Open public repository having all the public dependencies
• Goals:
  • install: copy the artifact into local repository
  • deploy: copy the artifact into remote repository
• Maven settings file: If we need to configure maven with remote repository location or other configuration details ~/.m2/settings.xml Refer Here for official docs
