Hm, I don't see that locally and haven't seen that one before. The automated builds also seem fine. The only difference I can see here is Windows, but I don't know why that would make a difference. scala-reflect is a direct dependency and should be added by mvn already.
Try deleting your ~./m2 or ~/.ivy dirs and try again? or at least all the artifacts downloaded for scala? very occasionally some artifact doesn't get correctly downloaded and you can get things like this.
