title: Jenkins issue with Trigger one build per property file
body: <p>Job A uses "For every property file, invoke one build" parameter factory to call downstream job B.
  Here is the file pattern I am using:
  d:\temp*.properties
  There are two files in that folder:
  build0.properties
  build1.properties</p>
  
  <p>each file looks something like this:</p>
  
  <pre><code>modified=SampleApp
  </code></pre>
  
  <p>Job B fails because job A is not setting the parameters from above file. If I look at the parameters for a build of Job B, they are empty.</p>
  
  <p>The process works when I use "Parameters from properties file" parameter type instead of a parameter factory, and specify the full path to one of the files, so I know the files are in the right format. I do not want to add a parameter for each file I have,
  since I will have these files generated dynamically.I would prefer to use the parameter factory if possible.</p>
