一. 在使用 jenkins  邮件拓展的过程中,邮件内容的变量找了好久,现把总结内容整理如下;

pipeline{
    agent{label 'master'}
    environment {
        
        gitpullerr = 'noerr'
        sendmail = 'no'

        git_key = '50e27d86-37e0-4a5b-82db-4ea5ea9492bf'
        git_branch = 'dev'
 
    }
    triggers { pollSCM('* * * * *') }
    stages {
   
        stage('Get Code') {

            }
        }

                    try {
                    
                       echo "${sdsdas}"
                    
                    }catch(exc) {
                        gitpullerr = 'err' ;
                        //throw exc
                    }
                    
                }
                echo "$gitpullerr"
            }  
        }
        stage('checkpullvalue'){
