release:prepare

Full name:

org.apache.maven.plugins:maven-release-plugin:3.0.1:prepare

Description:

Prepare for a release in SCM. Steps through several phases to ensure the POM is ready to be released and then prepares SCM to eventually contain a tagged version of the release and a record in the local copy of the parameters used. This can be followed by a call to release:perform. For more info see https://maven.apache.org/plugins/maven-release-plugin/usage/prepare-release.html.

Attributes:

  • Requires a Maven project to be executed.
  • Executes as an aggregator plugin.
  • The goal is not marked as thread-safe and thus does not support parallel builds.
