"custom checkbox parameter" plugin when I define it from the UI, it works perfectly.

 However, when I use the snippet provided by the Declarative Directive Generator.

I'm following the instructions as per the plugin documentation. Is this plugin not supported by dsl https://jenkinsci.github.io/job-dsl-plugin/# ?

no public field 'pipelineSubmitContent' (or getter method) found in class com.bluersw.CheckboxParameterDefinition
