"if you depend on only spring-core-2.0 and Acegi depends on spring-core-1.2.8, you're still going to have overlap of the classes in spring-core." No, Maven2 will recognize that it's the same artifact - and only one of them will be used on the classpaths, and the other ignored. That's the problem with "spring" vs "spring-core": maven2 won't recognize they provide the same classes. But "which one is resolved" is currently implemented as "the nearest to the pom" - which probably considered one of the top issues that need to be fixed. It should probably be something like "the dependency with the highest version number unless it's overwritten in the pom that depends on that dependency)".
