您可以执行以下操作：

pipeline {

    agent any
    environment {
        USER_PASS_CREDS = credentials('user-pass')
    }

    stages {
        stage('build') {
            steps {
                sh "cd .."
                sh('./script.sh ${USER_PASS_CREDS_USR} ${USER_PASS_CREDS_PSW}')
            }
        }
    }
}

credentials是通过使用凭据API和Credentials插件实现的。您的另一个选项是Credentials Binding插件，它允许您将凭据作为构建步骤的一部分：

stage('build with creds') {
            steps {
                withCredentials([usernamePassword(credentialsId: 'user-pass', usernameVariable: 'USERNAME', passwordVariable: 'PASSWORD')]) {
                    // available as an env variable, but will be masked if you try to print it out any which way
                    // note: single quotes prevent Groovy interpolation; expansion is by Bourne Shell, which is what you want
                    sh 'echo $PASSWORD'
                    // also available as a Groovy variable
                    echo USERNAME
                    // or inside double quotes for string interpolation
                    echo "username is $USERNAME"

                    sh('./script.sh $USERNAME $PASSWORD')
                }
            }
        }

希望这能帮上忙。
