The artifact weld-se is evil and should not be distributed at all.
The artifact weld-se-core is good.

Note that in this example myproject has direct dependencies on weld-se and weld-se-core for simplicity's sake, but in the real world, those are transitive dependencies.
Either way, mixing weld-se with weld-se-core or even just weld-se with slf4j-api will result classpath problems.
