Release Plugin

This is a Maven 3.x Plugin which is used by Apache Commons releases. See the Development page for information to help maintain this plugin.

The main purpose of the plugin is to automate the steps of our, namely The Apache Commons Project's, release process. Currently we have the mechanics for detaching distribution artifacts (i.e. all tar.gz artifacts and signatures as well as all .zip artifacts and signatures), creating a site.zip file, and staging all of those artifacts in a subversion repository (for the most part a sub directory of https://dist.apache.org/repos/dist/dev/commons/. It can, however, stage to any subversion repository.

Plugin Goals

Available Goals (which are meant to be used together; the only reason they are separated is for code readability):

  • commons-release:detach-distributions - Remove tar.gz, tar.gz.asc, zip, and zip.asc files from being uploaded to nexus and copy them to the target/commons-release-plugin directory.
  • commons-release:compress-site - Generate site.zip file in the target/commons-release-plugin directory.
  • commons-release:stage-distributions - Take all staged files in the target/commons-release-plugin directory, and the RELEASE-NOTES.txt from the root of the project, and commit them to a specified staging subversion repository.

Using the plugin

Configure the plugin as the last plugin in the<build> section of the pom.xml


After the above configuration performing the release would occur by (note. more in depth details can be found at Preparations For A Release):

  1. creating our release branch,
  2. checking compatibility,
  3. checking your dependencies,
  4. checking javadocs and code style,
  5. checking the apache license,
  6. configure the build to generate a complete set of release artifacts,
  7. preparing the release notes, updating the download file and other autogenerated files,
  8. tagging the release candidate, and
  9. running the following command:
    mvn -Duser.name=<yourApacheId> [-Duser.password=<yourApacheIdsPassword] [-DdryRun=true -Ptest-deploy] -Prelease clean test site deploy
If the component is new, then, before running this maven command, you would want to create the requisite subversion directory https://dist.apache.org/repos/dist/dev/commons/foo. Notice, that the way to perform a dry run of the release you need to include -DdryRun=true -Ptest-deploy.
