Hi Team,

I have configured two shared library under global pipeline section on Jenkins 2.414.2 to deploy in my UAT and Production environment using SCM.  Auto deployment is working fine for the environment. But when i added one more library to automated the Dev deployment it stopped working. All library contains same script only difference is environment name to deploy.  SCM is starting build but not able proceed, We are getting below error 

 
using GIT_SSH to set credentials
> git ls-remote -h – git@github.com:xxxxx.git # timeout=10
ERROR: Checkout failed
hudson.plugins.git.GitException: Command "git ls-remote -h – git@github.com:xxxxx.git" returned status code 128:

Please make sure you have the correct access rights
and the repository exists.

At a time only two library is working. Can someone guide me to resolve this issue.

Thanks.
