    - #### addVariable

          public void addVariable​(Environment.Variable var)

      get the variable list as an array
      Returns:
        array of key=value assignment strings
      Throws:
        `BuildException` - if any variable is misconfigured

    - #### getVariablesVector

          public java.util.Vector<Environment.Variable> getVariablesVector()

      Get the raw vector of variables. This is not a clone.
      Returns:
        a potentially empty (but never null) vector of elements of type Variable
