title: Dynamic parameter cannot be resolved in Gauge
body: <p>i try to use the <code>file</code> special parameter in a Gauge specification.</p>
  
  <pre><code>Export a customer
  ----------------------------------------
  * Find customer "Hans"
  * Export customer to &lt;file:/customer.xml&gt;
  </code></pre>
  
  <p>The java implementation for this looks like this</p>
  
  <pre><code>@Step("Export customer to &lt;file&gt;")
  public void test(String file) {
     System.out.println("file " + file);
  }
  </code></pre>
  
  <p>I assume the parameter typ is <code>String</code> (can it also be <code>File</code> ?)</p>
  
  <p>But nevertheless, running this, returns</p>
  
  <pre><code>[ParseError] C:\Users\user\IdeaProjects\qmsgauge\specs\tenantManagement.spec:40 
   Dynamic parameter &lt;file:/customer.xml&gt; could not be resolved =&gt; 'Export customer to &lt;file:/customers.xml&gt;'
  Successfully generated html-report to =&gt; C:\Users\user\IdeaProjects\qmsgauge\reports\html-report\index.html
  </code></pre>
  
  <p>How do I define the file parameter in the spec and how do need to write the java implementation for this ?</p>
  
  <p>Thanks</p>
