Examples

Input
agent any; env CI=true
Build: npm ci / npm run build
Test: npm test
Output

    stage('Build') { steps { sh 'npm ci' } }
  }
}

A declarative pipeline with one environment variable and shell steps.

About this tool

The Jenkins Pipeline Builder writes a declarative Jenkinsfile from a form. Set the agent, declare environment variables, add stages with shell steps, and optionally add post.always and post.failure actions. The output is a complete pipeline block you drop into your repo — nothing is uploaded.

How to use

  1. Set agent and env

    Pick an agent (any or a Docker image) and add KEY=VALUE environment variables.

  2. Add stages

    Each stage carries shell steps; they are wrapped in sh calls with single quotes.

  3. Copy the Jenkinsfile

    Commit the file to your repo and point a Jenkins pipeline job at it.

Use cases

Migration to Pipeline as Code

Replace freestyle jobs with a committed Jenkinsfile.

Common mistakes

Mistake:Unescaped single quotes in sh.

Fix:The builder escapes them, but keep shell quoting in mind when editing by hand.
