Make use of a shared library to reuse code across multiple jobs.

Setup instructions

1. In Jenkins, go to Manage Jenkins → Configure System. Under Global Pipeline Libraries, add a library with the following settings:

   • Name: jenkins-shared-library
   • Default version: main (branch)
   • Retrieval method: Modern SCM
   • Select the Git type
   • Project repository: <git repository url>
   • Credentials: select an existing credential

2. Then create a Jenkins job with the following pipeline:

   @Library('jenkins-shared-library') _
   
   stage('Demo') {
     common.sayHello("Rodrigo")
   }
   

Whenever a job is triggered, it will:

• clone this shared library repo (with most updated code)
• import the functions
• run whatever function you call in your pipeline
