title: Visual Studio Code Java compile multiple classes and import jar-s?
body: <p>I am switching from NetBeans to VS Code Java on Linux and I am unable to run or build my projects. I get <code>error: cannot find symbol</code> for every class declaration or external package usage.</p>
  
  <ul>
  <li>How do I build all the <code>.java</code> classes in a project folder, not just the currently opened one?</li>
  <li>How can I import <code>.jar</code> in VS code?</li>
  </ul>
