title: Eclipse - Extract/package the required libraries into the same Runnable JAR
body: <p>When exporting a project as a Runnable JAR file using Eclipse, there are three choices:</p>
  
  <pre><code>1. Extract required libraries into generated JAR
  2. Package required libraries into generated JAR
  3. Copy required libraries into a sub-folder next to the generated JAR
  </code></pre>
  
  <p>However, it seems that only one of the three choices could be chosen from the Runnable JAR File Export window. I wonder if there are some ways that could mix up these methods, e.g., extracting some of the files while packaging the rest?</p>
  
  <p>Note: I need this since one of my JAR file contains a ton of references to other files so 1 cannot be an option, and I am afraid that 2 might be causing some problems for me.</p>
  
  <p>Thanks!</p>
