I want to read a .json file in the stage Prepare Artifacts, which is there in workspace.

How can I read the workspace file path in the staging groovy and run the code?

The below code I used:

                    checkout scm: [
                        $class: 'GitSCM',
                        branches: [[name: "FETCH_HEAD"]],
                        extensions: [
                            [$class: 'RelativeTargetDirectory',
                                relativeTargetDir: repo2],
                            [$class: 'WipeWorkspace'],
                            [$class: 'CloneOption',
                                depth: 1,
                                noTags: true,
                                reference: '',
                                shallow: true,
                                honorRefspec: true],
                            [$class: 'CheckoutOption',
                                timeout: 30]],
                        gitTool: 'Default',
                        submoduleCfg: [],
                        userRemoteConfigs: [
                            [credentialsId: 'JENKINS_LOGIN',
                           ]
                        ]
                    ]
                    def releasePackages = readJSON file: "./BuildAutomation/Jenkins/Pipeline//files/release_package.json"
                    println releasePackages
                }
            }
        }


        stage('Prepare Variable') {
            steps {
                script{
                    
                        for(file in releasePackages[buildMod]['India']) {
                            bat("xcopy ..\\CALReleaseOutput\\${file} ..\\${IndiaReleaseOutputFolder}\\${file} /I /E /Y")
                        }

                        

for(file in releasePackages[buildMod]['Russia']) {
                                bat("xcopy ..\\CALReleaseOutput\\${file} ..\\${RussiaReleaseOutputFolder}\\${file} /I /E /Y")
                            }
                            
                            zip archive: false, dir: "..\\${b2bReleaseOutputFolder}", glob: '', zipFile: "..\\CALReleaseOutput_${tagFoldername}_B2B.zip"
                        }
                    }
                }
            }
            
        }
    }
}

When I run above one, I got error message as below Console Output

If you are going to use variables between stages you have to define them as Global variables. Hence try defining releasePackages outside the pipeline. Following is an example.

def releasePackages

pipeline {
    agent any

    stages {
        stage('SetVariable') {
            steps {
                script {
                    releasePackages = readJSON file: "./BuildAutomation/Jenkins/Pipeline//files/release_package.json"
                    echo "$releasePackages"
                }
            }
        }
        stage('UseVariable') {
            steps {
                   echo "$releasePackages"           
            }
        }
    }
}
