IllegalArgumentException when running ExampleMod for first time

I keep getting this error whenever I try to launch a mod through Eclipse. I only just started coding mods, so it's most likely a setup thing I'm missing. The full error is: 

Exception in thread "main" java.lang.IllegalArgumentException: Environment variable 'assetDirectory' must be set to a valid path.
	at net.minecraftforge.userdev.LaunchTesting.main(LaunchTesting.java:70)

Any help would be appreciated!
