Creating a GitHub Actions workflow

In this section, we will create a workflow that will build a Spring Boot Java application with GitHub Actions. This workflow will build a Spring Boot application using the mvn clean install Maven build tool command. The following is an example of a workflow file of building a Java project with Maven:

name: Build Java project with Maven
on:
  push:
    branches: [ main ]
  pull_request:
    branches: [ main ]
jobs:
  build:
    runs-on: ubuntu-latest
    steps:
    - uses: actions/checkout@v2
    - name: Install and Setup Java 16  
      uses: AdoptOpenJDK/install-jdk@v1
      with:
        version: '16'
        architecture: x64
