[FIXED] Jenkins conditional step for string contains

Issue

I am trying to do a conditional step on Jenkins to see if the String Parameter contains a certain word.

I have a string for PLATFORM. The values in it can be Windows, Mac, Linux

I want to run a certain step if the value of the parameter contains Linux.

How can I do that? I downloaded the Jenkins plugin for conditional step but it doesn't have a contains clause.

Solution

You can use when directive of Jenkins to achieve the conditional steps.

Example:

pipeline {
    agent any

    stages {
        stage ('Windows RUN') {
            when {
                expression { params.PLATFORM == 'Windows' }
            }
            steps {
                echo "Hello, Windows"
            }
        }
        
        stage ('Mac RUN') {
            when {
                expression { params.PLATFORM == 'Mac' }
            }
            steps {
                echo "Hello, Mac"
            }
        }
        
        stage ('Linux RUN') {
            when {
                expression { params.PLATFORM == 'Linux' }
            }
            steps {
                echo "Hello, Linux"
            }
        }
    }
}
