Exercise: Setting up agent to build jdk 17 and maven based softwares

sudo apt update 
sudo apt install openjdk-17-jdk maven -y

• Now navigate to project settings and agent pools
  
  
  
  
• Now configure account and permissions Refer Here
• Configure the agent according to the steps on documentation
  
  
• Now lets try to create a simple azure devops build pipeline

# Starter pipeline
# Start with a minimal pipeline that you can customize to build and deploy your code.
# Add steps that build, run tests, deploy, and more:
# https://aka.ms/yaml

trigger:
- main

pool:
  name: Default
steps:
  - bash: printenv

• Run the pipeline
