I guess if you are here it's because you have followed methodically all the examples but you keep having this annoying error message and you have no idea what it means. Of course there is no mention of it in the different examples and you are about to pull your hair out (well maybe I am overexagerating a little bit ). Don't worry there is hope. This trail presents the most common errors new users face when trying out Maven 2 for the first time. If you can't find the answers to your problems here, I strongly suggest you to post on the users mailing list or search in the archives.
