[INFO] Replacing /Users/elharo/workspaces/runtime-gcloud-eclipse/gf/target/gf-bundled-0.0.1-SNAPSHOT.jar with /Users/elharo/workspaces/runtime-gcloud-eclipse/gf/target/gf-0.0.1-SNAPSHOT-shaded.jar

We can probably cut some of the dependencies, perhaps upgrade others, and maybe push upstream to fix a few of these.
