title: How can I add a .jar to my build path in Eclipse?
body: <p>I try to do it the following way:</p>
  
  <ol>
  <li><p>Right click on the name of the project.</p></li>
  <li><p>Click on Build Path in the drop dawn menu.</p></li>
  <li><p>Click on "Configure Build Path"</p></li>
  </ol>
  
  <p>And then I do not know what to do. Should I select "Source", "Projects", "Libraries", "Order and Export"?</p>
  
  <p>In "Libraries" I have "Add JARs..." and "Add External JARs...". What should I select? (I have already a .jar file in the lib folder of my project.)</p>
  
  <p><strong>ADDED:</strong></p>
  
  <p>If I click on "Add JARs" in the "Libraries" tab, I see the "lib" sub-folder but if I go there I do not see my .jar file there (and I know that it is there).</p>
