Jenkins通过pipeline获取代码的时候，报错stderr: Host key verification failed. 报错日志如下：
[Pipeline] { (获取代码) [Pipeline] echo start fetch code from git: ssh://git@192.168.174.133:2222/Bruce/ops132.git [Pipeline] deleteDir [Pipeline] git Cloning the remote Git repository Cloning repository ssh://git@192.168.174.133:2222/Bruce/ops132.git > git init /var/lib/jenkins/workspace/ops132 # timeout=10 Fetching upstream changes from ssh://git@192.168.174.133:2222/Bruce/ops132.git > git --version # timeout=10 > git fetch --tags --progress ssh://git@192.168.174.133:2222/Bruce/ops132.git +refs/heads/*:refs/remotes/origin/* ERROR: Error cloning remote repo 'origin' hudson.plugins.git.GitException: Command "git fetch --tags --progress ssh://git@192.168.174.133:2222/Bruce/ops132.git +refs/heads/*:refs/remotes/origin/*" returned status code 128: stdout: stderr: Host key verification failed. fatal: Could not read from remote repository. Please make sure you have the correct access rights and the repository exists.手动在Jenkins主机上切换到Jenkins用户，执行git命令拉取代码，复现报错，没有权限
切换到Jenkins用户sudo su -s /bin/bash jenkins执行git命名拉取代码git clone ssh://git@192.168.174.133:2222/Bruce/ops132.git 报错没权限 jenkins@ubuntu:~/temp$ git clone ssh://git@192.168.174.133:2222/Bruce/ops132.git Cloning into 'ops132'...
