Jenkins Pipeline直接使用File parameter，无法将文件上传到当前job的workspace下面，需要通过调用第三方jenkinsci-unstashParam-library库实现，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: ‘输入上传war包‘) }
