When running my project from the IDE everything works fine, however when building it into a runnable jar file and trying to run the jar from the terminal, using <code>java -jar myjar.jar</code>, i got the following error:</p>

  <p>I'm currently using OpenJdk-1.8, i tried to use Oracle JDK v1.8 instead to build and then rerun the jar file, but still facing the same error. I'd also tried to create a new simple "Hello world" application and export a corresponding jar for it where it runs successfully without errors.</p>
  
  <p>Here is my jar internal structure and the corresponding manifist file:
