I don't know if this is a bug or I just don't know how to do it.  I'm using version 1.1.1 of the plugin.

In the rest of the jenkinsfile I can refer to variables with ${VARIABLE_NAME}

However, any variables within the SSH-steps command do not resolve.   Is there any way to feed these SSH-step commands variables?

i.e.

sshCommand remote: remote, command: "${ssh_cmd}"

This  SSH's and tries to run the command "${ssh_cmd}"  which of course fails.
