Why Use Shared Libraries in Jenkins Pipelines?
The article explains that shared libraries, a familiar concept from languages like Python, are implemented in Jenkins as Groovy classes containing methods, helping to centralize pipeline code, avoid bloated Jenkinsfiles, and improve maintainability, while also promoting a live broadcast and group chat.
Why Use Shared Libraries?
In fact, shared libraries are not a brand‑new concept; anyone with basic programming skills should already be familiar with them. For example, in Python you can place code in a file, package it as a module, and import the module’s functions when the code base grows.
In Jenkins, when using Groovy syntax, each file stored in a shared library is a Groovy class, and each class can contain one or more methods. Each method consists of a Groovy code block.
Now you may wonder how to achieve unified management of projects while writing pipelines with Jenkinsfiles, and how to prevent complex functionality from making Jenkinsfiles bloated and hard to maintain.
