For a first run, use Declarative syntax with a single echo step; it verifies the Pipeline setup without depending on a build tool installed on your agent.
What you need before creating a Pipeline
Jenkins Pipeline is a suite of plugins for defining and integrating continuous-delivery workflows. Jenkins’ getting-started documentation lists Jenkins 2.x or later and the Pipeline plugin as prerequisites; the suggested plugins in the post-installation setup wizard include Pipeline.
- A Jenkins controller where you can create or configure jobs.
- The Pipeline plugin installed.
- An available agent to execute the Pipeline if it uses an agent. An agent is a machine or execution node Jenkins assigns work to.
- For the source-control route, a project repository that Jenkins can access.
You can define a Pipeline in the classic Jenkins UI or store it as a Jenkinsfile in your repository. The syntax is the same in either case. For an evolving project, the repository approach makes the Pipeline definition versioned and reviewable alongside the project code. Jenkins’ “Creating your first Pipeline” documentation describes a Jenkinsfile checked into source control as the typical way to define a Pipeline.
Start with a minimal Declarative Pipeline

pipeline {
agent any
stages {
stage('Hello') {
steps {
echo 'Hello from Jenkins Pipeline'
}
}
}
}In Declarative syntax, the outer pipeline block contains the definition. agent any asks Jenkins to allocate an available execution agent and workspace. The stages block groups work; each stage has a readable name, and its steps block contains the actions Jenkins runs. Here, echo writes a message to the build’s console output.
A Declarative Pipeline needs a top-level pipeline block, an agent declaration, and stages containing steps. This example is intentionally only a first-run check; replace the message with commands appropriate to your project after confirming it runs.
Create and run a Pipeline from a Jenkinsfile
- At the root of your project repository, create a file named exactly
Jenkinsfile(no file extension). - Paste in the minimal example above, or adapt it for your project.
- Commit and push the file to the branch Jenkins should build.
- In Jenkins, create or configure a Pipeline job to load its Pipeline definition from source control. Select the repository and branch containing the Jenkinsfile; exact screen labels vary with Jenkins version and installed plugins.
- Save the job configuration and start a build. In the job page, use the available build action (often labelled Build Now) or the configured trigger.
- Open the build and inspect its stage view and console output. The
Hellostage should complete and the console should containHello from Jenkins Pipeline.
Jenkins’ Pipeline as Code guidance describes putting the Jenkinsfile in the repository root so Jenkins can discover and manage Pipeline jobs for repositories and branches.

Create and run a Pipeline in the classic UI
- From the Jenkins Dashboard, select New Item.
- Enter a job name and choose a Pipeline job type.
- In the job configuration’s Pipeline section, enter the minimal Declarative script in the Pipeline script field.
- Save the job, then start a build using the available build action, commonly Build Now.
- Open the build’s stage view or console output to check the result.
A script entered directly in the UI is stored in Jenkins’ home directory rather than in your project repository. That can be convenient for trying the first run, but the source-controlled Jenkinsfile route is easier to review and keep in step with code changes.

Turn the first run into project work
Once the message-only example succeeds, add commands and stages that actually exist in your build environment. The Jenkins deployment tutorial uses Build, Test, and Deploy as a basic continuous-delivery sequence. Treat that as an illustrative pattern, not a mandate: a project that does not deploy from Jenkins may need only build and test stages.
pipeline {
agent any
stages {
stage('Build') {
steps {
sh 'make'
}
}
stage('Test') {
steps {
// Replace with the test command for your project.
sh './run-tests'
}
}
}
}This illustrates the structure, not universal commands: use make only if it is installed and appropriate for the project, and replace ./run-tests with a real test command. Jenkins’ sh step runs Unix/Linux shell commands. On a Windows agent, use bat for Windows batch commands. A nonzero command exit code fails the Pipeline, which normally prevents later stages from running successfully.

For test reporting, Jenkins’ Jenkinsfile guidance demonstrates the junit step. It also documents archiveArtifacts for basic artifact retention; archiving in Jenkins is not a substitute for an external artifact repository when your delivery process requires one.
Choose syntax and agent placement
Declarative or Scripted
Declarative syntax gives a Pipeline a structured, opinionated form that is a readable starting point for straightforward workflows. Scripted Pipeline uses a limited form of Groovy and supports constructs such as conditionals, loops, and exception handling. Start with Declarative unless the workflow needs that additional flexibility; the two styles should not be confused as different job types.
One agent for the Pipeline or agents per stage
agent any at the top level runs the Pipeline on an available agent. You can use a label instead when the job needs a particular configured agent. A top-level agent none avoids reserving one agent for the whole Pipeline, but then each stage must declare its own agent. This is useful when stages need different configured environments; it also means you must ensure each requested agent is available.

Common first-run problems and fixes
- Jenkins rejects the Pipeline syntax: check that the Pipeline plugin is installed and that the Declarative structure is complete, including the top-level
pipeline, agent, stages, stage, and steps blocks. - The job cannot find the Jenkinsfile: confirm the file is named
Jenkinsfile, is at the repository root, and exists on the branch configured for the job. Check that Jenkins can access the repository. - The build waits for an agent:
agent anystill requires an available agent. Check that an agent is online and that any label used by the Pipeline matches a configured agent. - A shell command fails immediately: verify the command exists on that agent, runs from the expected workspace, and is valid for its operating system. Use
shon Unix/Linux agents andbatfor Windows batch commands. - A later stage does not run: inspect the earlier stage’s console output. A failed command, including one returning a nonzero exit code, can fail the Pipeline before subsequent work completes.
- The test stage runs but reports are missing: configure the project to produce test result files and use Jenkins’
junitstep with the appropriate report location.
Keep credentials and inputs safe
Jenkins’ Pipeline guidance documents credential helpers and warns that interpolating user-controlled values into a shell step can permit arbitrary code execution. Do not print secrets to the console, and do not interpolate untrusted input into shell commands. Use Jenkins credential mechanisms for secrets and validate or safely pass inputs rather than composing executable shell text from them.

ScreenshotNeo is a website screenshot API and MCP server, not a Jenkins runner; use Jenkins itself to create and execute the Pipeline above. If you need a screenshot of a rendered web page, ScreenshotNeo can capture it with one GET request. Its clean-shot processing accepts cookie or consent banners like a visitor and removes more than 60 known consent platforms, newsletter popups, and chat widgets before capture; each of those steps can be turned off. Bot checks or CAPTCHAs, blank pages, timeouts, failed loads, and cache hits cost nothing, and the response identifies the page verdict and billing status in headers. AI agents can use its MCP server tools, including take_screenshot, get_page_info, and capture_pdf.
For example, this cURL command saves a screenshot of Stripe’s website as WebP; replace the target URL with the page you want to capture. See the ScreenshotNeo API documentation for request options.

Frequently Asked Questions
Can I keep the Pipeline script in Jenkins and also use a Jenkinsfile?
Yes. Jenkins supports a script entered in a Pipeline job’s configuration as well as a Jenkinsfile loaded from source control; choose one definition source for a given job to avoid maintaining competing versions.
Does a Jenkins Pipeline have to include a Deploy stage?
No. Build, Test, and Deploy is an illustrative continuous-delivery sequence; include only the stages your project’s process needs.
Where do I see why a Pipeline failed?
Open the specific build’s console output and inspect the stage where execution stopped; it shows command output and the reported failure.
