How to execute the "Clone Issue" scriptrunner built-in script from within another scriptrunner script?

[Roberto Saltini]

I would like to execute the "Clone Issue" scriptrunner built-in script from within another custom scriptrunner script.

I tried something like this

import com.onresolve.scriptrunner.canned.jira.workflow.postfunctions.CloneIssue

Map params = [:]

params['issue'] = issue

params_after = CloneIssue.doScript((Map)params)

but I get the following error

groovy.lang.MissingMethodException: No signature of method: static com.onresolve.scriptrunner.canned.jira.workflow.postfunctions.CloneIssue.doScript() is applicable for argument types: (java.util.LinkedHashMap) values: [[issue:OTMCOPY1-44]] Possible solutions: doScript(java.util.Map), doScript(java.util.Map), doScript(java.util.Map), toString(), toString()

The doScript method isn't static, so you'll need to actually instantiate the CloneIssue class.

def cloner = new CloneIssue()
cloner.doScript([issue: issue ])

Hello! 

Is there some sort of documentation about how to use the cloneIssue function in another postfunction script other from these docs about using the built in function?

For e.g. the keys and values for the params map, 

controlling the copy of attachments, or 

using the doAfterCreate for issue linking or adding watchers? 

void cloneIssue (MutableIssue issue, Project project) {
 def params = [
 issue : issue,
 (CloneIssue.FIELD_TARGET_PROJECT) : project.key,
 (CloneIssue.FIELD_SELECTED_FIELDS) : null, //clone all the fields
 ] as Map<String, Object>
 
 new CloneIssue().doScript(params)
}

Greetings =)
