title: Jenkins Pipeline - Call functions in shared jar
body: <p>So here is my project setup</p>
  
  <ol>
  <li>A separate groovy project</li>
  <li>Multiple pipelines  </li>
  </ol>
  
  <p>All the pipeline scripts refer to the shared groovy project. I went through the shared libraries and all of the needs to be registered in Jenkins global configuration. </p>
  
  <p>Is there any way to do without it? I tried using Grab but ended up with the error</p>
  
  <pre><code>java.lang.RuntimeException: No suitable ClassLoader found for grab
  </code></pre>
