YAML for GIT Actions

In Git Actions, YAML files are used to define the steps of a workflow that is triggered by a specific event, such as a push to a Git repository. The YAML file specifies the actions that should be taken in response to the event, such as building and testing the code, deploying the code to a staging environment, or publishing the code to a production environment.

Here is an example of a simple YAML file for a Git Actions workflow that builds and tests a Java project:

name: Build and Test

on: [push]

jobs:
  build:
    runs-on: ubuntu-latest
    steps:
    - uses: actions/checkout@v2
    - name: Set up JDK 1.8
      uses: actions/setup-java@v1
      with:
        java-version: 1.8
    - name: Build with Maven
      run: mvn -B package
    - name: Test with JUnit
      run: mvn test

This workflow has a single job called "build" that is triggered by a push event. The job runs on an Ubuntu machine and performs the following steps:

1. Check out the code from the Git repository using the actions/checkout action.
2. Set up a Java Development Kit (JDK) version 1.8 using the actions/setup-java action.
3. Build the code using Maven with the mvn -B package command.
4. Test the code using JUnit with the mvn test command.

This is just a simple example, and Git Actions workflows can be much more complex and include multiple jobs and steps. You can also use third-party actions or create your own custom actions to perform specific tasks in a workflow.
