Currently there is no easy way to do this. You can find discussion about this in JENKINS-27413

Solution 2:^[2]

Yeah that parameter is as redundant as it can be. Might aswell just use string.

Anyway. You can get the files content with readFile:

def content = readFile encoding: 'utf-8', file: 'tomcatCodesUrl'

How to use file parameter in jenkins

This post might be helpful. The upshot is, when users upload a file, it will be saved into the root directory of the project's workspace. You can directly access the file using any programming language you like, given the file name. The file content is not returned to you as a parameter, but anyway, since you know its saved place (workspace dir) and file name, you are in control.
