How to accept ssh host verification in jenkins ssh agent

Question

Refer to following jenkins pipeline script

sshagent(['sshuser']) {
    sh "git clone ssh://[email protected]/test/test-commit.git"         
}

I am always getting following logs in jenkins

Cloning into 'test-commit'...
Host key verification failed.
fatal: Could not read from remote repository.

Tried a few tricks to auto accept the host verification but all failed, very frustrated.

If your main concern is with git you could use the GIT_SSH_COMMAND environment variable. It allows you to inject ssh options:

stage('My git stage') {
    environment {
        GIT_SSH_COMMAND = "ssh -o StrictHostKeyChecking=no"
    }
    steps {
        sshagent(['sshuser']) {
            sh "git clone ssh://[email protected]/test/test-commit.git"         
        }
    }
}

Mind you, this comes with some security concerns. You might want to investigate: https://www.symantec.com/connect/articles/ssh-host-key-protection
