How to stop passwords used by my scm plugin from appearing the log?

[Stuart Whelan]

My SCM plugin needs to call a command line client..

How can I stop the password being passed to the command line client from
appearing in the log?

I can see two directions to try, but I have not managed to find out to do
either:

1) Mask the password from the log..

2) Stop the launcher from outputing the command to the log... When I call
the launcher I use:
launcher.launch().cmds(argBuildr).envs(build.getEnvironment(TaskListener.NULL)).stdout(listener.getLogger()).pwd(workspace).join();


Any suggestions please?

Thanks!
Stuart.
