I'm using Jenkins pipeline CI. I'm using ssh-agent to push the build app to git but when I run the job I get build failure as

 

{{[Pipeline] { (push to git)

Jenkins script for pipeline is code script I used for jenkins pipeline is

 

{{stage('gitpush') {
steps{
sshagent (credentials: ['mygithubcredentialsID'])

{ sh("git clone https://github.com/mygithub/repository.git") }

sshagent (credentials: ['mygithubcredentialsID']) {

sh("(git add ranger-policies/policies.json)")
sh("(git commit -m 'daily backup of ranger-policies/policies.json')")
sh('(git push git@github.com:mygithub/repository.git)')
}

}
}
}}}

I'm using latest jenkins server on windows, I tried all the solutions available for similar kind of problems but none of them worked out, How can I fix this ? ssh-agent is running in back ground

$ if ps -p $SSH_AGENT_PID > /dev/null > then > echo "ssh-agent is already running" > # Do something knowing the pid exists, i.e. the process with $PID is running > else > eval ssh-agent -s > fi ssh-agent is already running
