Let's say you need to do something very slightly off the beaten path with Maven, like extract a single file from one of your dependencies so that it will be available to an XHR request in an offline web app as a static resource. No problem, just enter a quick 18 lines of XML.

But wait -- what if you're using Eclipse and M2E, and M2E decides that it doesn't know what to do about that dependency unpack you've just added? No problem, another 27 lines of XML oughta fix that.

Even though I know this to be true about Maven, every time I actually have to do it, it amuses me yet again.

Ah, Maven.
