A 'tag' translates to an Integrity CM Project Checkpoint with a project label and without cascading the label to all members. If you configure the Integrity - CM Checkpoint post-build action for a build configuration or if the Jenkins job is configured for a pre-build checkpoint, then the post-build action simply labels the project and does not attempt a new checkpoint. The PTC Integrity Plugin supports tagging with a user defined tag name/pattern. For example:
${env['JOB_NAME']}-${env['BUILD_NUMBER']}-${new java.text.SimpleDateFormat("yyyy_MM_dd").format(new Date())}
The following characters are not allowed within a 'tag':
$ , . : ; / \ @
