The SCM plugin provides some basic functionality for making releases, and updating the SCM accordingly. A release is performed in 2 steps:
Release preparation usually happens on an existing checkout. This checkout should be in such a state that with the exception of making final updates to the project.xml and changes.xml files, is ready to be released.
Preparing a release performs the following steps:
(Note that you may preview the changes made to project.xml and changes.xml by setting
When this operation is over, your source control has the released code tagged and ready to deploy.
The release is performed directly from source control. So while you can run it from an existing checkout to pick up it's SCM URL, it is not necessary and can be run like a checkout:
maven scm:perform-release -Dmaven.scm.url=scm:cvs:local:/cvs/root:module -Dmaven.scm.tag=RELEASE_1_0
You will be prompted for the tag and goals if they are not specified. The goals you give are what are required to deploy the release - the SCM side is all taken care of. For example, you might select to run the goals:
scm:perform-release checks out a clean copy of the code from the tag, and
runs the goals selected on the clean copy.
