dir() =

In a Jenkins Pipeline, dir() is a step used to change the working directory for the duration of a block of code. It’s especially useful in Declarative or Scripted Pipelines when you want to run certain steps inside a specific subdirectory of your workspace.

📁 Syntax Example (Declarative Pipeline)

`pipeline { agent any

stages {
    stage('Build') {
        steps {
            dir('my-subfolder') {
                sh 'mvn clean install'
            }
        }
    }
}

}`

🧠 What It Does

• Temporarily switches the working directory to my-subfolder.
• Executes all steps inside that block from that directory.
• After the block ends, Jenkins returns to the original workspace directory.
