Ssh
非互動式 SSH 連接失敗 - 錯誤：無法打開 /dev/tty：沒有這樣的設備或地址；主機密鑰驗證失敗
您可以在下面看到日誌。連接是從 Cygwin SSH 客戶端到 Cygwin SSHD 伺服器。從命令行啟動時連接正常，但從 Jenkins（Java 持續集成伺服器）啟動時連接失敗。/dev/tty 文件存在並且對每個人都是 rw。我嘗試刪除它並重新創建它，但我不能，因為 Cygwin 在創建指向 /dev/ttySO 的連結之前重新創建它。

您希望 Jenkins（Java 持續集成伺服器）如何輸入 ssh 密鑰的密碼？
如果這是開發或暫存環境並且沒有安全問題，您可以嘗試暫時從密鑰中刪除密碼，看看它是否工作得更好。
編輯＃1：
我可以重現您的問題的唯一方法是從 /dev/tty 中刪除權限，如 openssh faq 中所述，但我猜您已經檢查過了？
權限錯誤：
