title: javac option to compile all java files under a given directory recursively
body: <p>I am using the javac compiler to compile java files in my project. The files are distributed over several packages like this: <code>com.vistas.util</code>, <code>com.vistas.converter</code>, <code>com.vistas.LineHelper</code>, <code>com.current.mdcontect</code>.</p>
  
  <p>Each of these packages has several java files. I am using javac like this:</p>
  
  <pre class="lang-none prettyprint-override"><code>javac com/vistas/util/*.java com/vistas/converter/*.java
        com.vistas.LineHelper/*.java com/current/mdcontect/*.java
  </code></pre>
  
  <p>(in one line)</p>
  
  <p>Instead of giving so many paths, how can I ask the compiler to compile recursively all the java files from the parent com directory?</p>
