title: How can I add assets folder when I create jar in vscode?
body: <p>I have my java project that I want to compile to jar file. But when I look inside the created jar file I can't see my assets folder.
  My project structure looks like:</p>
  <pre><code>root/
  +- src/
  |  |
  |  +- default-package/
  |     |
  |     +- .java files
  |
  +- assets/
  </code></pre>
  <p>It also trows an error when I try to run it: <code>Error: A JNI error has occured...</code></p>
