title: Unable to export any of my projects into a .jar file
body: <p>Everytime I try to export any of the projects from my workspace into a Java jar file, I end up with an error:</p>
  
  <blockquote>
    <p>JAR creation failed. See details for additional information.
      Class files on classpath not found or not accessible for: 'Server Manager/src/me/Zahach/ServerManager/main.java'</p>
  </blockquote>
  
  <p>And this error is repeated for every class in my project.</p>
  
  <p>I tried reinstalling Eclipse, that didn't work.
  I then tried to recreate a project and drag and drop my packages into it, that didn't work either.</p>
  
  <p>What is going on?</p>
