Jenkins Pipeline使用File parameter

Jenkins Pipeline使用File parameter，将文件通过publish over cifs上传到Windows Share.

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：

1.访问 https://github.com/janvrany/jenkinsci-unstashParam-library ，下载zip压缩包，然后将其拷贝到Jenkins本机目录 /datafile/Jenkins2Library/jenkinsci-unstashParam-library，如下图：

2.Jenkins - 系统配置 - Global Pipeline Libraries，新增Library，但由于Jenkins设计，需要从远程git或scm拉去库，所以需要初始化本地 git 存储库并将其用作SCM来实现需求，而不需要任何远程主机git remote service，如下图所示

参考：https://www.jianshu.com/p/e1630651c95c

3.cd /datafile/Jenkins2Library/jenkinsci-unstashParam-library，然后 init a git repo 初始化git

git init
git add .
git commit -m "init"

4.检查git init 是否生效：

git status

/usr/bin/git ls-remote -h /datafile/Jenkins2Library/jenkinsci-unstashParam-library #在远程存储库中列出引用

以上完成后，在PipeLine中引用jenkinsci-unstashParam-library库即可，如下：

//引用jenkinsci-unstashParam-library
library "jenkinsci-unstashParam-library"
def file_upload
pipeline{
    agent any
    stages{
        stage("cifspub"){
            steps {
                script{
                    file_upload = unstashParam "myFileParam"
                    sh "pwd ${file_upload}"
                    println "curr file is: ${file_upload}"

                }
                
                //上传文件到Windows cifs share
                cifsPublisher(publishers: [[
                configName: 'CifsShare_10.10.3.21', //cifs share name
                transfers: [[cleanRemote: false,
                excludes: '',
                flatten: false,
                makeEmptyDirs: true,
                noDefaultExcludes: false,
                patternSeparator: '[, ]+',
                remoteDirectory: "$JOB_NAME/$BUILD_ID", //remote directory
                remoteDirectorySDF: false,
                removePrefix: '',
                sourceFiles: "${file_upload}" ]], //file parameter
                usePromotionTimestamp: false,
                useWorkspaceInPromotion: false,
                verbose: true]]
                )
                
            }
        }
    }
}
