    Description

      When empty Job Parameter passed though jenkins to invoke gradle script, it do not evaluate to empty but takes parameter name in gradle script.

       

      Steps to reproduce: 

      1. Passing empty parameter to jenkins job

      2. Executing gradle script using Job parameter 

      3. Job execution takes job parameter to be literal, while expected empty

       

      Might be a regression from : https://issues.jenkins-ci.org/browse/JENKINS-42573

          Another effect of this bug:

          Gradle step with Tasks: "task1 task2 $PARAM_1"

          In 1.26 this worked even if PARAM_1 was empty, gradle received an empty string in its place.  

          in 1.27.1 this fails (unknown task "$PARAM_1")

          Same for the Switches field, I have jobs with $PARAM_1 either set to "" or to "-i", for example.  This no longer works.

           

          All of the above used to work in 1.26.  I know that Token Macro Plugin is not the problem here because all of the above still works great in Maven Steps.

          Log:
          Don't remove empty build vars

          By utilizing the EnvVars.overrideAll(Map) method, it internally removes keys where the value is null or an empty string. This results in those parameters not being rewritten to empty properties as expected and the properties instead have the jenkins replacement string in them instead.

          [FIXES JENKINS-45300]
