Password with special character in the scripted Jenkins pipeline for 7z command

Question

I am working on a scripted Jenkins pipeline. I have stored a secret in Credential plugin. I want to use that secret when creating an achieve using 7z. Here is my code:

stage('Zip and Encrypt Artifacts') {
   withCredentials([string(credentialsId: 'encryption_key', variable: 'SHARED_PASSWORD')]) {
      archive = report.replace(".txt",".7z")
      sh "7z a -p${SHARED_PASSWORD} -mhe ${archive} ${report}"
      sh "rm ${report}"
   }

}

This code works with simple password. But, it fails with strong password. What is your suggestion? How should I change the sh command?

thanks.

Answer 1

Quote all your variables:

    sh '''
        7z a "-p${SHARED_PASSWORD}" -mhe "${archive}" "${report}"
        rm "${report}"
    '''

Note that you need to use single quotes around the script so you can use double quotes inside it. You have to use double quotes in the shell command so that variables will be expanded.
