changelogs empty in multi-node environment due to syncID calculation

Title: Message Title

I forgot to add information on the workaround - which is simple enough : explicitly define the syncID yourself for each workspace in a p4 sync operation.

Any static String will do as long as it is unique within the Jenkins instance, and doesn't depend on the node name, executor number or build number (in other words, it has to remain constant across builds).

Generally speaking, $JOB_BASE_NAME should work quite well as basis for the value (provided you don't have jobs with the same name in different folders - which may be allowed by Jenkins), but when the job is renamed there may be a single build where the changes will be empty. Subsequent builds will have proper changelists again.

$JOB_NAME might work too, but will produce a build with empty changes when the job is renamed or moved to a different folder. Also, since the String is a path, you might want to clean up special characters such as slashes to be safe, although I'm not running into any issues ATM.

This translates into the checkout step as follows : (in this case, using only $JOB_BASE_NAME, there's only a single checkout in this script)

 
                                                                checkout perforce(
  credential: 'myCreds',
  populate: autoClean( ... ),
  workspace: manualSpec(
    charset: 'utf8',
    name: "$env.P4CLIENT",
    pinHost: false,
    spec: clientSpec( ... ),
    syncID: "${JOB_BASE_NAME}"
  )
)
