Drools support in IntelliJ IDEA
<p>I'm trying to use IntelliJ IDEA with legacy project with Drools files but I'm not successful in this.</p>

<p>I added <a href="http://www.drools.org" rel="noreferrer">Drools framework</a> to the module with <code>*.drl</code> files and... nothing. I can't reformat <code>*.drl</code> files, don't have any navigation, no code completion etc.</p>

<p>I expected to see ability to add Drools facet to my module, specify <code>*.drl</code> files and then work with Drools files basically as with Spring framework.</p>

<p>So what Drools support actually IntelliJ IDEA has? </p>
