How to make .jar library from sources
<p>I have Tapjoy sources sources, which have such sructure: <code>Tapjoy/src/com/tapjoy/*.class</code></p>

<p>It must be compiled with Android API Level 9 and higher.
My project is in version Android API Level 8.</p>

<p>So I need to make from sources of <code>Tapjoy -&gt; tapjoy.jar</code> file and include it to my main project.</p>

<p>How can I make <code>.jar</code> file properly with command line or from eclipse?</p>
