[JENKINS-34105] Add support for parameters of type java.util.Set #272

TriggerOnSpecifiedImageNames from the Docker Hub Notification plugin has a parameter with type Set<String>, see source.

Instantiation will fail due to argument type mismatch when passing a Groovy list literal. It would be nice if the list would be coerced to a set automatically.


import org.jenkinsci.plugins.registry.notification.opt.impl.TriggerOnSpecifiedImageNames 
import org.jenkinsci.plugins.structs.describable.DescribableModel

def m = new DescribableModel(TriggerOnSpecifiedImageNames)
m.instantiate([repoNames: ['foo', 'bar']])



java.lang.IllegalArgumentException: argument type mismatch
