Answer a question

The Extended Choice Parameter plugin is great and I use it in jobs configured via the UI https://wiki.jenkins-ci.org/display/JENKINS/Extended+Choice+Parameter+plugin

However, I'm struggling to get it working in a Jenkinsfile style pipeline script. It would appear that the Extended Choice Parameter plugin isn't yet fully compatible with Pipeline scripts since Jenkins pipeline-syntax generator creates the following snippet:

parameters([<object of type com.cwctravel.hudson.plugins.extended_choice_parameter.ExtendedChoiceParameterDefinition>])

If I create the parameters manually I get the same behavior as mentioned in https://issues.jenkins-ci.org/browse/JENKINS-32188

org.kohsuke.stapler.NoStaplerConstructorException: There's no @DataBoundConstructor on any constructor of class 

Does anyone know of any workarounds that can get around the issue of ExtendedChoiceParameterDefinition not using @DataBoundConstructor?

• Jenkins 2.19.2
• Extended Choice Parameter plugin 0.75

Since April's 2nd, 2019 it's now possible because of this commit: https://github.com/jenkinsci/extended-choice-parameter-plugin/pull/25

You can use it like this for instance:

properties([
    parameters([
        extendedChoice( 
            name: 'PROJECT', 
            defaultValue: '', 
            description: 'Sélectionnez le projet à construire.', 
            type: 'PT_SINGLE_SELECT', 
            groovyScript: valueKeysScript,
            descriptionGroovyScript: valueNamesScript
        )
    ])
])

If you want to know every possible parameter you have to refer to the source code. If you want to know every possible value for the "type" key, have a look at the PT_* constants.
