The correct credential ID for folder scope is folder-cred. Using an incorrect ID causes errors.

Fill both blanks to create a folder-scoped credential and use it in a Jenkins pipeline.

Jenkins

folder('MyFolder') {
  credentials {
    usernamePassword {
      id = '[1]'
      username = 'user1'
      password = 'pass1'
    }
  }
}

pipeline {
  agent any
  stages {
    stage('Use Folder Credential') {
      steps {
        withCredentials([usernamePassword(credentialsId: '[2]', usernameVariable: 'USER', passwordVariable: 'PASS')]) {
          sh 'echo $USER'
        }

Using different IDs for definition and usage.

Both blanks use folder-cred to define and reference the folder-scoped credential.

hard

Fill all three blanks to define a global credential, a folder credential, and use the folder credential in a pipeline.

Jenkins

credentials {
  usernamePassword {
    id = '[1]'
    username = 'admin'
    password = 'adminpass'
  }
}

folder('ProjectFolder') {
  credentials {
    usernamePassword {
      id = '[2]'
      username = 'projuser'
      password = 'projpass'
    }
  }
}

pipeline {
  agent any
  stages {
    stage('Run') {
      steps {
        withCredentials([usernamePassword(credentialsId: '[3]', usernameVariable: 'USER', passwordVariable: 'PASS')]) {
          sh 'echo $USER'

Common Mistakes

Mixing up global and folder credential IDs.
