我是 jenkins 的新手，我试图使用凭证和管道建立 ssh 连接。 当我使用 ssh 等插件时， easy2 SSH， 我能够连接到远程主机并执行任何 shell 命令。 但要求是使用管道脚本，不幸的是出现错误。
代码：
pipeline {
agent any
stages {
stage('deploy app and reports') {
steps {
script {
withCredentials ([sshUserPrivateKey(credentialsId: 'oracle', keyFileVariable: 'identity', passphraseVariable: '', usernameVariable: 'oracle')]) {
def remote = [:]
remote.name = "friendly name"
remote.host = "ip address"
remote.allowAnyHosts = true
remote.user = 'prasad'
remote.identityFile = identity
sshCommand remote:remote, command: "ls -l"
sshCommand remote:remote, command: 'ls -l'
sshCommand remote:remote, command: 'pwd'
}
}
}
}
}
}
错误：

明白了，通过安装 ssh steps 插件解决了这个问题。
