Part 2: Diving into Pull Requests with Bitbucket

---

Introduction to Bitbucket and Pull Requests

Bitbucket is an Atlassian product that provides Git code management and collaboration tools. A pull request in Bitbucket allows you to propose changes to a codebase, facilitating discussions, reviews, and eventually, the merging of those changes into another branch. Let’s explore how to utilize Bitbucket’s capabilities to the fullest when it comes to pull requests.

Creating a Pull Request in Bitbucket

Creating a pull request is straightforward in Bitbucket. After pushing your branch, navigate to your repository on the Bitbucket web interface.

1. Click on “Pull requests” in the left-hand menu.
2. Click on “Create pull request.”
3. Select the source and destination branches.
4. Add reviewers, set approval rules if necessary, and create the pull request.

Automated Checks with Bitbucket and Jenkins

Bitbucket can easily be integrated with Continuous Integration tools like Jenkins to perform automated checks. Here’s a sample Jenkinsfile that can be included in your repository to run checks when a pull request is created:

pipeline {
    agent any

    stages {
        stage('Checkout') {
            steps {
                checkout scm
            }
        }
        stage('Build and Test') {
            steps {
                script {
                    // Add your build and test scripts here
                }
            }
        }
    }

    post {
        always {
            // Actions to always perform
        }
        success {
            // Actions to perform on success
        }
        failure {
            // Actions to perform on failure
        }
    }
}Code language: JavaScript (javascript)

In Jenkins:

1. Create a new job and select “Bitbucket hook trigger for GITScm polling.”
2. In the Pipeline configuration, select “Pipeline script from SCM” and provide your Bitbucket repository URL.

Once set up, Jenkins will automatically trigger a build whenever a pull request is created or updated, and the build status will be displayed within Bitbucket.

Approving and Rejecting Pull Requests

You can set up approval rules in Bitbucket to specify how many approvals are required before a pull request can be merged. After a pull request has the necessary approvals and all automated checks have passed, it can be merged.

To reject a pull request:

1. Go to the pull request.
2. Leave a comment explaining the reason for rejection.
3. Click “Decline.”

By declining a pull request, you’re ensuring that the proposed changes do not get merged into the target branch. This is a useful feature when a pull request introduces changes that are either incorrect or not aligned with project goals.
