title: Shared libraries "vars" folder structure - can I add subfolders?
body: <p>From <a href="https://jenkins.io/doc/book/pipeline/shared-libraries/#directory-structure" rel="noreferrer">Extending with Shared Libraries - Directory structure</a> I created a shared library where I have multiple *.groovy files implementing global variables in the vars folder.</p>
  
  <p>Can I add subfolders to vars to organize better my files? I tried, with no luck at the moment of consuming the global variable. Is there a specific syntax I need to use to reference a file in a subfolder? or subfolder are just not supported?</p>
