What is GitHub Actions?
GitHub Actions is a continuous integration and continuous delivery (CI/CD) tool that allows you to automate your software build, test, and deployment pipeline. It’s a powerful tool that helps you to streamline your development workflow, reduce manual errors, and increase the speed of your software delivery. With GitHub Actions, you can create custom workflows that automate tasks such as building and testing your code, creating and deploying packages, and even sending notifications.
Main Features of GitHub Actions
Some of the key features of GitHub Actions include:
- Customizable workflows: Create custom workflows that fit your specific needs and automate tasks that are unique to your project.
- Integration with GitHub: GitHub Actions is tightly integrated with GitHub, making it easy to automate tasks such as building and testing your code, creating and deploying packages, and more.
- Support for multiple languages: GitHub Actions supports a wide range of programming languages, including Java, Python, JavaScript, and more.
Installation Guide
Step 1: Create a GitHub Actions Workflow File
To get started with GitHub Actions, you’ll need to create a workflow file that defines the tasks you want to automate. This file is typically named `.github/workflows/main.yml` and is stored in the root of your repository.
Here’s an example of a simple workflow file that builds and tests a Java project:
| Filename | Contents |
|---|---|
| .github/workflows/main.yml | name: Java CI |
Step 2: Configure Your Workflow
Once you’ve created your workflow file, you’ll need to configure it to run on specific events, such as when code is pushed to your repository.
You can do this by adding an `on` section to your workflow file, like this:
on:
push:
branches:
- main
