Demonstrates how to use a Shared Library in Jenkins pipelines. This repository defines a single function, sayHello, which will echo a greeting.

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

   • Name: pipeline-library-demo
   • Default version: Specify a Git reference (branch or commit SHA), e.g. master
   • Retrieval method: Modern SCM
   • Select the Git type
   • Project repository: https://github.com/monodot/pipeline-library-demo.git
   • Credentials: (leave blank)

2. Then create a Jenkins job with the following pipeline (note that the underscore _ is not a typo):

   @Library('pipeline-library-demo')_
   
   stage('Demo') {
   
     echo 'Hello World'
   
     sayHello 'Dave'
   
   }
   

This will output the following from the build:

[Pipeline] stage
[Pipeline] { (Demo)
[Pipeline] echo
Hello world
[Pipeline] echo
Hello, Dave.
[Pipeline] }
[Pipeline] // stage
[Pipeline] End of Pipeline
Finished: SUCCESS
