How can I load credentials.json file into jenkins pipeline job?

Question

I have a script which runs against google Directory API.

The purpose of this script is to download all users from Google's Directory of our company.

But when I run that script it give an error

FileNotFoundError: [Errno 2] No such file or directory: 'credentials.json'

Although that file is in the folder.

Do I need to put that file into the Credential manager or ....?

I also have a groovy file which just install the pip and activate venv and nothing else.

Here is groovy code

stage('Check activity') {
      steps {
        sh 'pwd'
        sh '''#!/bin/bash
          set -e
          if ! which pipenv >/dev/null; then
              echo \'no pipenv, installing...\'
              pip3 install --user pipenv
              if ! which pipenv >/dev/null; then
              # default location for: /home/jenkins/.local/bin/pipenv
              my_pip_env="/home/${USER}/.local/bin/pipenv"
              fi
          else
              echo \'pipenv already installed, nothing to do.\'
              my_pip_env=$(which pipenv)
          fi
          # pipenv version, check & install
          ${my_pip_env} --version
          ${my_pip_env} install
          # run script
          PYTHONPATH=$(pwd):${PYTHONPATH} \\
          PIPENV_PIPFILE=$(realpath ./Pipfile) \\
          ${my_pip_env} run -v python3  ./it/google-users/google_user.py -v "${VERSION}" -dr "${DRY_RUN}" -et "${EXCLUDED_TYPES}"
          # Remove virtualenv project
          ${my_pip_env} --rm
        '''
      }
    }

do I need to define environment variables in groovy script?

When reading a file from your workspace, it is best to use readFile function

readFile('credentials.json')

In your case, you could read it into a variable and then pass it into the next steps of your script. Something like this:

pipeline {
    agent any
    stages {
        stage('Check activity')
        {
            steps {
                script {
                    sh '''#!/bin/bash
                       echo "hello" > hello.txt
                    '''
                    def mydata = readFile('hello.txt')
                    sh "echo My file data: ${mydata}"
                }
            }
        }
    }
}
