This checks all changes are committed, and prompts for a tag and version name to release the project with. It will update project.xml locally and in the SCM system, as well as tagging the SCM as requested. scm:perform-release This task checks out the project from SCM at any location, from the tag requested. It then builds a clean version of the code and deploys it to the remote repository. You can automate this using the appropriate properties, but for any that are not provided you will be prompted for them.
