I'm not in depth in Mahout at all, but I already did some similar "clean dependencies" task on maven project. For sure depencies analysis cannot tell the whole things and only in depth unit test and deployment allow you to ensure that you got all that is needed. For some libraries such as Logging you may suppose that those are provided in the deployement environement and thus you could remove them (or set them as "provided").
Well, I provide no clear answer, but just do it slowly and one-by-one or you may end up with a mess. cheers On Mon, Feb 8, 2010 at 15:33, Robin Anil <robin.a...@gmail.com> wrote: > But the whole thing is compiling without those jars.
