Overage charges	Not applicable	Storage: $0.008/GB/day[1]Minutes:- Linux: $0.008/min- Windows: $0.016/min- macOS: $0.08/min[5]

Workflow YAML

• Refer Here for structure

• Workflow has
  • Events: Which trigger workflow
  • Jobs:
    • Each job executes on a runner
    • job consists of steps
      • A step can be acheived
        • actions
        • run

First Workflow : Spring petclinic

• Whenever developer raises a pull request execute mvn package
• Refer Here for repository

# This workflow will build a Java project with Maven, and cache/restore any dependencies to improve the workflow execution time
# For more information see: https://docs.github.com/en/actions/automating-builds-and-tests/building-and-testing-java-with-maven

# This workflow uses actions that are not certified by GitHub.
# They are provided by a third-party and are governed by
