In the previous tutorial, I discussed the Jenkins pipeline. This tutorial will discuss the steps to create the Jenkins pipeline for Gradle Project.

Pre-Requisite:

Jenkins was installed and started on the computer.

Implementation Steps

Step 1: Create a new pipeline project.

1. Give the Name of the project – Gradle_PipelineDemo
2. Click on the pipeline project. 
3. Click on the OK button.

In the General section, enter the project description in the Description box.

Step 2: Scroll down to Pipeline

From the Definition field, choose the “Pipeline script from SCM” option. This option instructs Jenkins to obtain your Pipeline from Source Control Management (SCM), which will be your locally cloned Git repository.

From the SCM field, choose Git.

The Repositories section contains the Repository URL and Credentials.

In the Repository URL field, specify the directory path of the GitLab/GitHub project.

In the Credentials field, specify the username and password needed to log in to GitLab/GitHub.

In this case, I have the project is present in GitLab and using it.

Step 3: Create Jenkinsfile

Create and save a new text file with the name Jenkinsfile at the root of the project in the GitLab repository. Here, we are using the Gradle project with Serenity. To know more about the Integration of Gradle with Serenity, please refer to this tutorial – Serenity BDD with Gradle and Cucumber for Web Application

For this tutorial, we are using Declarative syntax. The sample example is given below

pipeline {
    agent any
 
    stages {
        stage('Test') {
            steps {
                bat "gradle clean test"
            }
 
            post {                
                // If Gradle was able to run the tests, even if some of the test
                // failed, record the test results and archive the jar file.
                success {
                   publishHTML([
                      allowMissing: false, 
                      alwaysLinkToLastBuild: false, 
                      keepAll: false, 
                      reportDir: 'lib/target/site/serenity/', 
                      reportFiles: 'index.html', 
                      reportName: 'Serenity Report', 
                      reportTitles: '', 
                      useWrapperFileDirectly: true])
                }
            }
        }
    }
}

Step 4: Specify branches to build a section under Repositories.

1. Branch Specifier – */main(This is my main branch)
2. ScriptPath – Jenkinsfile

Click on the Apply and Save buttons.

We have created a new Maven project “Gradle_PipelineDemo” with the configuration to run the Selenium Test with TestNG.

Step 5: Execute the tests

Let’s execute it now by clicking on the “Build Now” button. 

Right-click on Build Number (here in my case it is #6) and click on Console Output to see the result.

Below is the test execution summary.

Step 6: Pipeline Steps

Once the execution is completed, and we want to see the Pipeline Steps, click on the Pipeline Steps mentioned on the left side of the page.

Step 7: View the Report

Once the execution is completed, go back to “Gradle_PipelineDemo“. We can see below that the Serenity Report is generated. To know, how to generate Serenity Report, please refer to this tutorial – How to create Jenkins pipeline for Serenity tests

We could see a link to view the “Serenity Report“. Click on the Serenity Report. It displays the Serenity Report.

Tip: If you don’t see the Report UI intact, then you need to configure a simple groovy script. For that, go to Dashboard–>Manage Jenkins–>Script Console and add the script as:

System.setProperty("hudson.model.DirectoryBrowserSupport.CSP","")

That’s it! Congratulations on making it through this tutorial and hope you found it useful! Happy Learning!!
