title: Debug into Maven Dependency Source w/IntelliJ
body: <p>I'm debugging a Maven project in IntelliJ and I'm trying to figure out how to step into the source of one of my dependencies that's specified in my pom.xml.  Specifically, my project has a dependency on Crawler4J I'm seeing some weird behaviour from Parser.parse(), and I want to step thru that method.  I tried setting up a local cloned Git repo with the source and attaching it via the Sources option under Project Structure, but I still can't step into the compiled Crawler4J methods.  As a long time C# developer (and relative Java nub) what I would have ideally liked is something like .NET Reflector's functionality for decompiling on the fly while debugging, but a way to attach the source would suffice.</p>
