The Eclipse Plug-in works best with AEM 6.3. I found previous versions were buggy - for 6.2 articles - we used Maven Archetype 10, Eclipse, and compiled using the command line.
For those reading this - use Lazybones to create a 6.3 project - see:

Now for 6.2 - use Maven Archetype 10 as discussed here:
