Use RestApiScriptRunner with auto generated DSL?

[denisrosca]

This is more of a question than an issue, but I was wondering if it is possible to use the RestApiScriptRunner to execute a dsl configuration containing calls to a "auto generated" dsl?
I have a use case where a seed job tries to create a jenkins job containing a slack notifier:

job {
	publishers {
		slackNotifier {
			room('my-slack-room')
			notifyAborted(true)
			notifyFailure(true)
			notifyNotBuilt(true)
			notifyUnstable(true)
			notifyBackToNormal(true)
			notifySuccess(false)
			notifyRepeatedFailure(true)
		}
	}
}

I get the following exception:

Caused by: javaposse.jobdsl.dsl.DslScriptException: (script, line 45) No signature of method: javaposse.jobdsl.dsl.helpers.publisher.PublisherContext.slackNotifier() is applicable for argument types: (script$_run_closure1_closure4_closure10_closure11_closure12) values: [script$_run_closure1_closure4_closure10_closure11_closure12@76884e4b]

The root cause seems to be that the slack plugin uses the automatically generated dsl feature, thus the 'slackNotifier' method is not present when executing the script using the rest runner.

I think I encountered something very similar, I have code that works well under Jenkins but it fails with a similar groovy.lang.MissingMethodException: No signature of method.

This should be able to reproduce it:

def xxx() {
}
