Maven 3.0.2 - WAR File is duplicating dependant JARS in two places

When I run: "mvn package -skipTests" from the command line to create my WAR file, Maven copies my dependent jars into WEB-INF/lib, and then copies them again into the root of the WAR. So I end up with the same files in two different places. I've stripped my pom.xml down to the bare essentials, but the duplicates still occur.
