I have created simple pipeline and would like to copy it with logged_in_user name.  I am accepting logged_in_user value from parameter but while copying it is creating new job with same name instead of variable value. It Seems replace string is not working properly. 

Initial line from build is as follows:

Started by user
Deepak Arora
Running as
Deepak Arora
Building in workspace /var/lib/jenkins/workspace/Copy
Copying Patching to Patching_Progress/{user}
Already exists: Patching_Progress/{user}
Fetching configuration of Patching...
