example of SCPClient

RemoteSCP.groovy

    String runCommandWithOutput(Connection connection) {
        log.trace("SCP command to place ${file} on ${host} at ${remotedir}")
        output = new StringBuilder()
        try {
            SCPClient scp = connection.createSCPClient()
            scp.put(file, 0, remotedir, "0600")
            connection.close()
            output.append("File $file should now be copied to $host:$remotedir\n")
        }
        catch (Exception e) {
            log.error("Unable to copy ${file} to ${host}:${remotedir}", e)
            output.append(e.message)
        }
        return output.toString()
    }

This is what I get in my logs:

I then end up with a blank file on my server

If you wanted to see the RemoteConnection file that is also being used to get the Connection it can be found here: https://github.com/michaelrice/RemoteSSH/blob/devwork/src/groovy/grails/plugin/remotessh/RemoteConnection.groovy
