Jenkins Pipeline编译错误排查：propagate参数语法问题

错误提示 #

错误：org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed: WorkflowScript: 164: unexpected token: , @ line 164, column 33. , propagate:false

问题根源 #

编译错误来自install_fugazi_new_image阶段的build步骤，存在两处语法违规：

• parameters参数的闭合括号)后错误换行，导致propagate:false被Groovy解析为独立无效语句
• propagate:false前多了一个逗号，违反Groovy方法调用的语法规范

修正后的代码片段 #

将install_fugazi_new_image阶段的build步骤调整为如下正确形式：

stage ("install_fugazi_new_image") {
    when { expression {FUGAZI_PLATFORM_VAR} }
    steps {
            script { 
                def IMAGE_FILE_VAR = FUGAZI_IMAGE_FILE_PATH_VAR.split("/").last()
                def TESTBED_FILE = "./curie/testbed_files/Fugazi_${TESTBED_NAME_VAR}.yaml"
                def INSTALL_IMAGE_ARGS = "./job_files/image_upload_job.py --testbed-file  ${TESTBED_FILE} --image_file ${IMAGE_FILE_VAR} --mail-to ${MAIL_TO_VAR}"
                echo "args for install_new_image= ${INSTALL_IMAGE_ARGS}"

                build job: "/team_eng_ent_routing/CURIE/Helper_Projects/PYATS_JOB_EXECUTOR", parameters: [
                string(name: "pyats_job_args", value: INSTALL_IMAGE_ARGS),
                string(name: "branch_name", value: BRANCH_NAME_VAR),
                string(name: "platform_name", value: "FUGAZI ${TESTBED_NAME_VAR}")
                ], propagate:false
            }            
    }
}

核心修改：删除parameters闭括号后的多余换行和逗号，让propagate:false作为build方法的参数直接衔接在参数列表后。
