Maven build Life Cycle:
======================
Each of these build lifecycles is defined by a different list of build phases, wherein a build phase represents a stage in the lifecycle.
    validate - validate the project is correct and all necessary information is available
    compile - compile the source code of the project
    test - test the compiled source code using a suitable unit testing framework. These tests should not require the code be packaged or deployed
    package - take the compiled code and package it in its distributable format, such as a JAR.
    verify - run any checks on results of integration tests to ensure quality criteria are met
    install - install the package into the local repository, for use as a dependency in other projects locally
    deploy - done in the build environment, copies the final package to the remote repository for sharing with other developers and projects.===============

    node {
       stage('Prepare') {
          git 'https://github.com/cicdTrainer/spring-boot-demo.git'
       }
       stage('Compile') {
          sh "'/usr/bin/mvn' -Dmaven.test.failure.ignore clean compile"
       }
    }
4- Save
5- Go to job and build

=============   
Master/Slave:
=============
1- Go to Jenkin Home Page
2- Go to Manage Nodes
3- Add Node
4- Name/Level : test
5- Select Connect Master vai Websoket
6- Save
7- Clink on Test Node
8- Download agent.jar [it is hyper link, hover over agent.jar]
9- Copy the `java -jar ...` command display on page.
    - Ex: sudo java -jar agent.jar -jnlpUrl http://localhost:8080/computer/test/slave-agent.jnlp -secret fef4874372892b1f433b4356ef2aa5cef09d3dbd52cef61dff314be99448f381 -workDir "/var/jenkins" 
10- Go to slave machine and open termianl and run the `java -jar ...` command
11- Check the terminal/console log. At last it should log `connected`.
12- Check Manager node page again. Now there is no red mark in test node.

===============================================
Step up Pipeline which run on `test` slave node:
===============================================
1- Create a new item using pipeline template.
2- Go to script section and copy the below script [ agent {label 'test'} is the conf which uses for Node selection to excute a pipeline]
 pipeline {
  agent any
  stages {
    stage('Stage 1') {
      steps {
        echo "${env.NODE_NAME}"
      }
    }
    stage('Stage 2') {
      agent {label 'test'}
      steps {
          echo "${env.NODE_NAME}"
      }
    }
  }
}
