title: Why is the run button not working in Eclipse?
body: <p>I have built a code that does not have errors. It has ran on several occasions throughout adding various components, but for some reason, it will not run anymore. When I click the arrow, Eclipse shows the hourglass and then it goes away and does not do anything. How can I make it run so that I can test the program?</p>
  
  <p>Thanks for any helpful assistance. </p>
