Why the multiple downloads of the same jar?

[Russel Winder-4]

For the Gant build I am using a locally installed build of Groovy Trunk.
Whenever I rebuild Groovy and then use Gradle to build Gant, I get:

|> gradle libs

Clearly the item must be downloaded from the local Maven repository to
Gradle's Ivy repository, but why do it multiple times.  This seems
completely senseless and a total waste of resources.
