使用OR关系进行JSR-303验证(JSR-303 validation using an OR relationship)

 在参数块中定义您的参数： 
 
pipeline {
    agent any

    parameters {
        string(defaultValue: 'us-west-2', description: 'Provide your region', name: 'REGION')
    }


    stages {
        stage('declarative'){
            steps {
                print params.REGION
                 sh "echo ${params.REGION}"
            }
        }

        stage('scripted'){
            steps {
                script {
                    print params.REGION
                }
            }
        }
    }
}
 
 输出： 
 
[Pipeline] {
[Pipeline] stage
[Pipeline] { (declarative)
[Pipeline] echo
us-west-2
[Pipeline] sh

[test] Running shell script
+ echo us-west-2

Define your parameters in a parameter block:
 
pipeline {
    agent any

    parameters {
        string(defaultValue: 'us-west-2', description: 'Provide your region', name: 'REGION')
    }


    stages {
        stage('declarative'){
            steps {
                print params.REGION
                 sh "echo ${params.REGION}"
            }
        }

        stage('scripted'){
            steps {
                script {
                    print params.REGION
                }
            }
        }
    }
