Apache Apex minimum development environment
<p>I am wondering what the minimum environment I need to develop and test my Apex apps?</p>

<p>Running in <code>Eclipse</code> on <code>Windows</code>, I generated <code>Apex</code> project using the Apex archtype  and tried to run the default <code>JUnit</code> test that gets created but get the following error:</p>

<blockquote>

<p>What else do I need to have installed to get a dev environment up and running? Is <code>Hadoop</code> required for JUnit tests like this?</p>
