[SOLVED] write all parameters jenkins in JSON file using ${params}

Issue

I'm a beginner with shell scripting and i have some issues while a jenkins job parametrized. I want to write all parameters of jenkins job pipeline build with parameters into a JSON file using ${params}! In my case i have 4 parameters(apis:multi-select,name:string,version:single-select and status:Boolean), there is the script Jenkinsfile

pipeline {
  agent any
    stages {
        stage('Build') {              
            steps {              
                script{              
                   sh "./test.sh ${params}"
                }
            }
        }
    }
}

Content of test.sh

#!/bin/bash
echo $@ > file.json

The output in jenkins

+ ./test.sh [apis:dev,qa,prod, name:CC, version:g3, status:true]

Result in file.json

SyntaxError: JSON.parse: unexpected character at line 1 column 2 of the JSON data

My question is how format the output to obtain a clean result in file.json ? please i need help.

Solution

Add this to the top of your script:

import groovy.json.JsonOutput

Then use this line instead of sh "./test.sh ${params}":

writeFile file: 'params.json', text: JsonOutput.toJson(params)

This uses a Groovy library and a native Jenkins method for writing files, which means you don't need to use the sh method.
