Why Use Shared Libraries in Jenkins Pipelines?
The article explains the concept of shared libraries, compares them to Python modules, describes how Jenkins uses Groovy classes for reusable pipeline code, and highlights their role in simplifying and standardizing Jenkinsfile management while also promoting an upcoming live event.
Why Use Shared Libraries?
Shared libraries are not a brand‑new concept; developers with programming experience should already be familiar with them. For example, in Python you can place code in a file, package it as a module, and import its functions when the codebase grows.
In Jenkins, 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 that you have an understanding of shared libraries, you may wonder how to achieve unified project management while writing pipelines with Jenkinsfiles, and how to prevent complex functionality from making Jenkinsfiles bloated and hard to maintain.
