So, a bunch of the API's used in the Mojo Developers Cookbook have been marked "deprecated" in maven 3.0. ArtifactFactory and ArtifactMetadataSource for instance.
http://docs.codehaus.org/display/MAVENUSER/Mojo+Developer+Cookbook
Another one I use a lot is WagonManager.
I poked around the maven source code for about an hour and couldn't figure out
what replaces ArtifactFactory. Anyone else going to Maven 3.0 run into this or
just ignore the warnings...
