Manage a webhook with Jenkins configuration in GitHub

To manage a webhook with Jenkins configuration in GitHub, follow these steps:

Install and Set Up Jenkins: If you haven't already, install Jenkins on your server or local machine and set it up following the necessary steps for your environment.

Install Required Jenkins Plugins: Install the necessary plugins in Jenkins to enable integration with GitHub. Some commonly used plugins include "GitHub Integration Plugin," "GitHub Organization Folder Plugin," and "GitHub Pull Request Builder Plugin."

Create a GitHub Personal Access Token: To allow Jenkins to interact with your GitHub repositories, you'll need to generate a personal access token on GitHub. Go to your GitHub account settings > Developer settings > Personal access tokens, and create a new token with the required permissions (usually repo and admin:repo_hook).

Set Up GitHub Credentials in Jenkins: In Jenkins, navigate to "Manage Jenkins" > "Manage Credentials" > "Jenkins" (global domain) > "Add Credentials." Provide your GitHub username as the "Username" and paste the personal access token you generated in the "Password" field. Give the credentials an ID (e.g., "github-credentials") and save them.

Create a Jenkins Job: Create a new Jenkins job to build and test your GitHub repository. Configure the job with the necessary build steps and test commands.

Configure GitHub Webhook: In your GitHub repository, go to "Settings" > "Webhooks" > "Add webhook." Set the Payload URL to your Jenkins server URL (e.g., http://your-jenkins-server/github-webhook/). Choose "application/json" as the content type, and add the "push" event or any other events you want to trigger the Jenkins build. Optionally, you can choose to enable SSL verification if your Jenkins server has a valid SSL certificate.

Add Jenkins GitHub Integration: In the Jenkins job configuration, under "Build Triggers," select "GitHub hook trigger for GITScm polling." This enables Jenkins to start the job automatically whenever a push event is received from the GitHub webhook.

Save and Test: Save your Jenkins job configuration and test the webhook by pushing changes to your GitHub repository. Jenkins should automatically trigger the job and start the build process.

That's it! Your Jenkins job is now configured to be triggered by the GitHub webhook whenever changes are pushed to the repository. Jenkins will fetch the latest changes, build the project, and execute any defined test scripts, providing continuous integration and automation for your GitHub repository.

Maven Create and Build Artifacts

In Maven, you can create and build artifacts using the package phase of the build lifecycle. The package phase is responsible for taking the compiled code and other project resources and packaging them into a distributable format, such as a JAR (Java Archive), WAR (Web Application Archive), or other custom formats. Here are the steps to create and build artifacts using Maven: Configure the Build Output: In your project's pom.xml file, you need to configure the output of the build. This includes specifying the type of artifact you want to create (e.g., JAR, WAR) and any additional resources to include. You do this in the <build> section of your pom.xml: <build>     <finalName>my-artifact</finalName> <!-- Name of the artifact without the extension -->     <plugins>         <!-- Plugin configurations for creating the artifact -->         <!-- For example, maven-jar-plugin or maven-war-plugin -->     </plugins> </build> Depend

Experiment No. 5 Title: Applying CI/CD Principles to Web Development Using Jenkins, Git, and Local HTTP Server

  Experiment No. 5 Title: Applying CI/CD Principles to Web Development Using Jenkins, Git, and Local HTTP Server  Objective: The objective of this experiment is to set up a CI/CD pipeline for a web development project using Jenkins, Git, and webhooks, without the need for a Jenkinsfile. You will learn how to automatically build and deploy a web application to a local HTTP server whenever changes are pushed to the Git repository, using Jenkins' "Execute Shell" build step. Introduction: Continuous Integration and Continuous Deployment (CI/CD) is a critical practice in modern software development, allowing teams to automate the building, testing, and deployment of applications. This process ensures that software updates are consistently and reliably delivered to end-users, leading to improved development efficiency and product quality. In this context, this introduction sets the stage for an exploration of how to apply CI/CD principles specifically to web development using J
