Groovy JSON Parsing: Filter Values with Pattern Matching Name2-develop-FullPackage

Parsing and filtering JSON data can be challenging, especially when you're just starting with a programming language like Groovy. If you've come across a situation where you need to extract values based on a specific pattern, you're in the right place. This guide will guide you through the process of parsing JSON in Groovy, focusing on filtering values that match the pattern Name2-develop-FullPackage.

The Problem

You have a JSON string containing information about different builds. Your objective is to filter this data to only include builds that start with the name Name2-develop-FullPackage and store these results in an array.

Given JSON Example

Here’s the JSON structure you’ve been working with:

The Solution

The solution lies in properly parsing the JSON data and using the Groovy capabilities to filter the array of builds based on their display names.

Step-by-Step Explanation

Parse the JSON String:
Use JsonSlurper to convert the JSON string into a usable object in Groovy.
