title: Jenkins How can i upload a text file and use it as a parameter
body: <p>I have a txt file that is holding a string inside, I want to be able to use this string in one of my scripts, so I'm wondering if there is a way to set the content of the file as one of the build properties or parameters which I'll be able to use in my scripts it should be the same as using one of the build environment properties.
  For example : ${JOB_NAME} which is holding the the job name, so in the same way I want to access the content of the file which is holding some value inside.
  Is it possible?</p>
