The clean  install and deploy phases are valid lifecycle phases and invoking them will trigger all the phases preceding them  and the goals bound to these phases       mvn clean install   This command invokes the clean phase and then the install phase sequentially    clean   removes files generated at build-time in a project s directory  target by default  install  installs the package into the local repository  for use as a dependency in other projects locally       mvn deploy   This command invokes the deploy phase    deploy  copies the final package to the remote repository for sharing with other developers and projects       mvn release   This is not a valid phase nor a goal so this won t do anything  But if refers to the Maven Release Plugin that is used to automate release management  Releasing a project is done in two steps  prepare and perform  As documented      Preparing a release goes through the   following release phases          Check that there are no uncommitted changes in the sources   Check that there are no SNAPSHOT dependencies   Change the version in the POMs from x-SNAPSHOT to a new version  you   will be prompted for the versions to   use    Transform the SCM information in the POM to include the final   destination of the tag   Run the project tests against the modified POMs to confirm everything is   in working order   Commit the modified POMs   Tag the code in the SCM with a version name  this will be prompted   for    Bump the version in the POMs to a new value y-SNAPSHOT  these values   will also be prompted for    Commit the modified POMs      And then      Performing a release runs the   following release phases          Checkout from an SCM URL with optional tag   Run the predefined Maven goals to release the project  by default    deploy site-deploy       See also   Introduction to the Build Lifecycle The Maven Release Plugin
