Have you used common libraries or Jenkins Shared Libraries when automating CI/CD processes?

Yes, in automating CI/CD processes, I used Jenkins Shared Libraries to create reusable scripts and functions, which helps standardize pipelines and reduce code duplication. For example, common build, testing, and deployment steps can be extracted into a library, and in the Jenkinsfile, these functions are simply called.

Example of using a Shared Library in Jenkinsfile:

@Library('my-shared-library') _

pipeline {
    agent any
    stages {
        stage('Build') {
            steps {
                common.build()
            }
        }
        stage('Test') {
            steps {
                common.test()
            }
        }
    }
}

Where common is a class or set of functions from the shared library.
