Jenkins通过SSH进行文件传输

Jenkins 使用ssh 传输文件的插件很多，比如SSH plugin， SCP publisher，Publish Over SSH，pipeline脚本可以用 SSH Pipeline Steps，如果你不想用插件，也可以直接通过命令进行复制

Jenkins 使用Publish Over SSH插件传输文件如图所示，文件路径为相对路径
可以使用pipeline 脚本为

sshPublisher(
	publishers: [
		sshPublisherDesc(
			configName: '30.208', 
			transfers: [
				sshTransfer(
					cleanRemote: false, 
					excludes: '', 
					execCommand: '', 
					execTimeout: 120000, 
					flatten: false, 
					makeEmptyDirs: false, 
					noDefaultExcludes: false, 
					patternSeparator: '[, ]+', 
					remoteDirectory: '/home/software/microservice-docker-jars', 
					remoteDirectorySDF: false, 
					removePrefix: 'target', 
					sourceFiles: 'target/*.jar'
				)
			], 
			usePromotionTimestamp: false, 
			useWorkspaceInPromotion: false, 
			verbose: true
		)
	]
)

使用 SSH Pipeline Steps 插件并结合withCredentials 如下：

def remote = [:]
remote.name = "node-1"
remote.host = "10.000.000.153"
remote.allowAnyHosts = true

node {
    withCredentials([sshUserPrivateKey(credentialsId: 'sshUser', keyFileVariable: 'identity', passphraseVariable: '', usernameVariable: 'userName')]) {
        remote.user = userName
        remote.identityFile = identity
        stage("SSH Steps Rocks!") {
            writeFile file: 'abc.sh', text: 'ls'  #写入脚本
            sshCommand remote: remote, command: 'for i in {1..5}; do echo -n \"Loop \$i \"; date ; sleep 1; done'
            sshPut remote: remote, from: 'abc.sh', into: '.'
            sshGet remote: remote, from: 'abc.sh', into: 'bac.sh', override: true
            sshScript remote: remote, script: 'abc.sh'
            sshRemove remote: remote, path: 'abc.sh'
        }
    }
}

sshPut 正则匹配写法如下：

sshPut remote: remote, from: './target/', filterRegex: /\.jar$/, into: '/data/software/jars'

但是sshPut 在实际使用过程中，当我们利用正则匹配匹配target下的jar包，无法仅复制文件夹中的文件。总是将整个文件夹复制过去，该插件没有给出很好的解决方案 (或许可以使用filterBy，filterRegex参数进行过滤，感兴趣的可以试试)。
比较好的解决方案如下：

findFiles(glob: 'Build/rpms/*.rpm').each { rpmFile -> 
  sshPut remote: remote, from: rpmFile.path, into: '/data/mirror/rpm-repo'
}

findFiles依赖插件：Pipeline Utility Steps，否则会报错：java.lang.NoSuchMethodError: No such DSL method ‘findFiles’ found among steps

原因：sshPut执行超时
解决方法：修改pipeline脚本中SSH Pipeline Steps 相关的remote配置，参考
增加： remote.timeoutSec = 60
