Scriptrunner: How to include custom scripts with "issue" object

Question

I`ve got a "library" with common functions, .../scripts/util/Helper.groovy:

package util

import .......

public class Helper {
    public String getCurrentProjectKey() {
       return issue.projectObject.key
    }
}

And a script .../scripts/myscript.groovy:

import util.Helper

def helper = Helper

String currentProjectKey = helper.getCurrentProjectKey()

I use it as a post-function. But everytime I get an error or while checking either when running. The main problem is that "issue" object is not seen in library. I use different combination of code to make the "issue" object be recognizable, but nothing helps me...

For example, error:

file:/var/atlassian/application-data/jira/scripts/util/Helper.groovy: 29: Apparent variable 'issue' was found in a static scope but doesn't refer to a local variable, static field or class. Possible causes:
You attempted to reference a variable in the binding or an instance variable from a static context.
You misspelled a classname or statically imported field. Please check the spelling.
You attempted to use a method 'issue' but left out brackets in a place not allowed by the grammar.

How can I use "issue" object in my imported common libraries?

Or how can I get the current issue object?

Thanks in advance.

Hey Maksim,

Sure, you can. So in that case the Helper class will be

import com.atlassian.jira.issue.MutableIssue

class Helper {

private MutableIssue issue

Helper(MutableIssue issue) {
this.issue = issue
    }

String getCurrentProjectKey() {
issue.projectObject.key
    }
}

And then you script will look like

import myExampleScripts.util.Helper

def helper = new Helper(issue)
def projectKey = helper.getCurrentProjectKey()

log.debug "Project Key is $projectKey"

I edited my first answer in order to make it more readable.

Hello Thanos!

Thank you for reply, I will try your advice,

I want to use common methods like getCurrentProjectRoles and others. I use different scripts, so I dont want to use same code in every script.

Is it possible to do something like:

import myExampleScripts.util.Helper

def helper = Helper(issue)

def currentIssueAssignee = helper.getCurrentIssueAssignee()

Is there any way an issue object to give to the class on its init and then use it in functions?

Hi Maksim,

I suppose one way is to pass the issue as a parameter. For example your Helper class would be something like

import com.atlassian.jira.issue.MutableIssue

class Helper {

static String getCurrentProjectKey(MutableIssue issue ) {
        issue.projectObject.key
    }

}

and then your script something like

import static myExampleScripts.util.Helper.*

def projectKey = getCurrentProjectKey()

log.debug "Project Key is $projectKey"

PS. I would be really interested to know what kind of helper methods you use ...

Kind regards,

Thanos
