Example of code reuse using classes

LinkUtils.groovy

This class contains a utility method that will search all work items in a given space and summarize the key and number of blockers against each work item that is blocked.

package utils 
class LinksUtils {
 static Map<String, Integer> getBlockedItemsByProject(String project) {
        Issues.search("project = ${project}").collectEntries {
 def blockers = it.getLinks().findAll {  it.type.inward == 'is blocked by'}.collect()
 return [(it.key) : blockers.size()]
        }.findAll {
            key, value -> value as int > 0
        }
    }
}

We can use the above code in a script as follows:

import utils.LinksUtils

LinksUtils.getBlockedItemsByProject('DEMO')

package utils - In Groovy, a package reflects the parent folder structure of the code's location. The package helps Groovy identify a class, and you need to reference it when importing code into your scripts. For example, you can see how we imported the code for reuse using the following statement: import utils.LinksUtils

Example of code reuse using scripts

Groovy also allows us to import and reuse scripts without the need to declare classes. There are multiple options for doing this.

reusablescript.groovy

A simple Groovy script that defines a method that takes an argument called name and returns a greeting.

package com.myapp.simplescripts

println "Script loaded!"
def greet(name) { "Hello, $name!" }

Importing and reusing a part of the script:

import com.myapp.simplescripts.reusablescript
 
def script = new reusablescript()
script.greet('Admin')

You can call specific methods declared in the script, or you can use .run() to run the entire script. Using a script works similarly to using a class because, in the background, each .groovy file automatically becomes a class you can instantiate.
