我们正在尝试通过Jenkins作业构建iOS应用程序，但我们无法从我们的Gitlab实例克隆存储库。到目前为止，当git获取引用时，Jenkins会挂起(直到10分钟超时)。
下面是Jenkins的输出:

我们已经添加了Mac的SSH公钥作为存储库的部署密钥，并使用Mac的SSH私钥作为凭据，但由于某种原因，它无法工作。任何想法吗?
编辑:查看Mac slave上的日志，我注意到它提示用户"为密钥'/var/folders/92/<RANDOM STRING OF CHARACTERS>/T/ssh<RANDOM STRING OF NUMBERS>key':"输入密码，如果我手动输入SSH密钥的密码，它就会工作。"然而，这个解决方案对于自动构建系统来说并不理想。
进一步挖掘，如果我实际进入'/var/folders/92/<RANDOM STRING>/T/'文件夹，我看到一些文件。当Mac slave被提示输入密码短语时，会出现一个ssh<RANDOM NUMBERS>key文件、一个ssh<DIFF RANDOM NUMBERS>.sh文件和一个pass<OTHER DIFF RANDOM NUMBERS>.sh文件。ssh<...>key文件包含SSH私钥，ssh<...>.sh文件包含使用该私钥的SSH命令，pass<...>.sh文件包含回显SSH口令的命令。
原来我需要将SSH密钥添加到Mac的密钥链中，或者删除SSH密钥中的密码。为了添加到密钥链，在Mac上运行ssh-add <SSH PRIVATE KEY FILE>(您可能还需要启用ssh-agent执行eval $(ssh-agent))。
我的猜测是你的Jenkins从属进程与你从命令行运行git时使用的用户不同。如果是这样的话，在Jenkins中运行git之前，你需要批准这个用户的初始主机密钥验证。(你知道-你第一次连接SSH时得到的消息:
)The authenticity of host '111.11.11.11' can't be established.
RSA key fingerprint is 3f:1b:f4:bd:c5:aa:c1:1f:bf:4e:2e:cf:53:fa:d8:59.
Are you sure you want to continue connecting (yes/no)?
