如何在Jenkins管道脚本中访问触发器事件属性

pipeline {
    agent any
    stages {
        stage('Example') {
            steps {
                script {
                    def causes = currentBuild.rawBuild.getCauses()
                    for (cause in causes) {
                        if (cause instanceof hudson.model.Cause.UserIdCause) {
                            def userId = cause.getUserId()
                            println "User ID: ${userId}"
                        } else if (cause instanceof hudson.triggers.SCMTrigger.SCMTriggerCause) {
                            def commit = cause.getShortDescription()
                            println "Last commit: ${commit}"
                        }
                        // 添加其他触发器事件的处理逻辑
                    }
                }
            }
        }
    }
}
