Support labels without associated resources

XMLWordPrintable

      Currently, you need at least one resource for a label.
      When I try to lock on a label and no resource exists (yet) for that label, pipeline fails with

       

      java.lang.IllegalArgumentException: The resource label does not exist: my_label.
at org.jenkins.plugins.lockableresources.LockStepResource.validate(LockStepResource.java:95)
at org.jenkins.plugins.lockableresources.LockStep.validate(LockStep.java:183)
at org.jenkins.plugins.lockableresources.LockStepExecution.start(LockStepExecution.java:43)

      use case:
      I want to create a pool of resources (testsystems btw) to be used in a build pipeline. The resources are created on-demand by a separated groovy-script job.
      During nighttimes the pool will be completely empty though, and the build pipeline will so fail hard instead of waiting for the next resource

          My workaround is now to create a dummy lock (i.e. one without an associated testsystem) and reserve the lock indefinitely

          Alternative approach would be to skip the label validation when trying to acquire a lock on a label.
          Then any label name should be accepted - irrespective if a resource already exists for that label
