Replacing all new line charc in a file with a special character "#" in groovy

Question

How to replace all "\n" occurrences in a text file with "#" using groovy in a jenkins pipeline

Answer 1

This should work. Use the find operator ~ in Groovy

def parsedText = readFile("input.groovy").replaceAll(~/\n/, "#")
writeFile file: "output.groovy", text: parsedText

EDIT If you use Declarative Pipeline Syntax, the working code is as follows:

pipeline {
    agent any
    stages {
        stage ('Print'){
            steps {
                script {
                    def inputText = readFile file: "1.groovy" 
                    inputText = inputText.replaceAll(~/\n/, "#")       
                    writeFile file: "2.groovy", text: inputText
                }
            
            }
        }
    }
}
