title: Eclipse-JAR creation failed "Class files on classpath not found or not accessible for", " Exported with compile warnings" and "duplicate entry"
body: <p>I download (pull) an update code of my project from bitbucket and then when I try to export a Runnable JAR File, I got the following errors. I try to solve my problem based on these pages <a href="https://stackoverflow.com/questions/4378074/duplicate-entry-error-when-exporting-java-project-to-jar-with-eclipse">1</a> <a href="https://stackoverflow.com/questions/9108124/what-causes-duplicate-entry-warnings-when-jaring-with-eclipse">2</a> and <a href="https://stackoverflow.com/questions/18300815/eclipse-jar-creation-failed-class-files-on-classpath-not-found-or-not-accessi">3</a>. But, I could not find any solution. </p>
  
  <p>I want to run my code on server so  How can I solve this problem? </p>
  
  <p>I do not know how can I find duplication of the LICENSE.txt file  and other duplication files.</p>
  
  <pre><code>JAR creation failed. See details for additional information.

  <p>When I chose <em>package required libraries into generated JAR</em> instead of <em>Extract required libraries into generated JAR</em> all duplicate entry errors are disappeared but I still have other errors.</p>
