Jenkins ssh-steps-plugin 身份验证失败

我正在尝试使用 ssh-steps-plugin 来构建一个使用 SSH 在远程机器上写入文件的管道。 我使用 PEM 生成了一个 SSH 密钥，并在远程服务器上复制了公共密钥（使用 ssh-copy-id），这样我就可以成功连接到服务器： > 

ssh -i private-keys debian@192.168.0.59

现在，我写了这个简单的管道（在插件的 github repo 上找到了相同的管道）：

def remote = [:]
remote.name = "debian"
remote.host = "192.168.0.59"
remote.allowAnyHosts = true

node {
    withCredentials([sshUserPrivateKey(credentialsId: 'debian-id', keyFileVariable: 'identity', passphraseVariable: '', usernameVariable: 'debian')]) {
        remote.user = debian
        remote.identityFile = identity
        stage("SSH Steps Rocks!") {
            writeFile file: 'abc.sh', text: 'ls'
            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'
        }
    }
}

我将凭据 debian-id 添加到 globals 凭据，并且我的远程机器的用户名是 debian

当我尝试执行管道时出现此错误。

我尝试了很多次来稍微更改脚本，但总是出现相同的错误。我尝试将 usernameVariable 从 userName（如示例所示）更改为 debian，但无论如何都不起作用。

我做错了什么？

我的解决方案

此错误似乎与带密码的 ssh 密钥有关。生成一个没有密码的新密钥我可以成功连接

太好了！它对我有用。

如果您需要更改 (1) 密码和 (2) 将密钥转换为 Old Openssh 运行（在您的密钥所在的目录中）：

ssh-keygen -p -f id_rsa -m pem

--> 输入旧密码（回车） --> 留空以删除密码（输入）
