Jenkins Pipeline直接使用File parameter，無法將檔案上傳到當前job的workspace下面，需要通過呼叫第三方jenkinsci-unstashParam-library庫實現，方法如下：

sharedlibraries地址：https://github.com/janvrany/jenkinsci-unstashParam-library

unzip jenkinsci-unstashParam-library-master.zip -d ./
mv  jenkinsci-unstashParam-library-master  jenkinsci-unstashParam-library

cd /data/tools/jenkinsci-unstashParam-library 
git init
git add .
git commit -m "init"

git status 
/usr/bin/git ls-remote -h /data/tools/jenkinsci-unstashParam-library

jenkins configure system

在pipeline中引用sharedlibraries

@Library('jenkinsci-unstashParam-library') _
import hudson.model.*;

pipeline {
    agent {
        label 
 
'master'
    }

    environment {
    
        HARBOR_CREDS = credentials('149fd0b9-5156-4e46-b6bf-196049cb464a')

    }
    
    parameters {
        
        file(name: 'jenkins.war', description: '輸入上傳war包')

    }
