JENKINS-37400

I want to use constant values in workflow-cps like

def runWrapper = selectRun job: 'upstream-project-name', 
  selector: status(SUCCESSFUL)

This change requires jenkinsci/structs-plugin#11. Build will fail.

[ikedam]

As this requires jenkinsci/structs-plugin#11.

Build will fail.

mvn -DskipTests deploy dependencies.

mvn -DskipTests deploy dependencies.

That means deploying a snapshot release with jenkinsci/structs-plugin#11 to maven.jenkins-ci.org, doesn't it?
I've run a build and a test in my environment by running mvn install.
I don't think it's a good idea to deploy a plugin with local changes even if it's a snapshot release, and I'll do that at least after jenkinsci/structs-plugin#11 is merged.

Yes, we do that all the time for chained PRs.

Abondon the review.
I'll try another way.
