change label by certain condition

Objective :

add the keyword marslo_ as prefix of labels whose label isn't belongs to keyword list.

prevent repeat to add :

  • List keyword = [ 'project1', 'project2', 'keyword', 'marslo_' ]
  • or
  • r.setLabels( 'marslo_' + r.labels.split('marslo_').last() )

import org.jenkins.plugins.lockableresources.*

LockableResourcesManager manager = org.jenkins.plugins.lockableresources.LockableResourcesManager.get()
List keyword = [ 'project1', 'project2', 'keyword' ]

manager.getResources().findAll { r ->
  r.labels && ! keyword.any{ r.labels.toLowerCase().startsWith(it) }
}.collect { r ->
  r.setLabels( 'marslo_' + r.labels.split('marslo_').last() )
}
  • show result
