Typesafe Stack play-scala Example Unresolved Dependencies OSX Homebrew Install

Question

Got a fresh Homebrew install of scala, giter8, sbt (0.11.3), and maven and everything checks out for the most part. brew doctor shows just known mods I've made by installing pcre and python 2.7 manually. When I get the play-scala template and then run it for the first time, I get the following unresolved deps on slf4j

# sudo sbt run
...

What is the proper way to prevent this? Shouldn't these deps be downloaded during initialization?

Thanks!

Answer 1

Thanks to this question I ended up deleting ~/.m2 and ~/.ivy2, then did clean, update, reload. Subsequently everything worked. The update command successfully retrieved slf4j:

[my_app] $ update
[info] Updating {file:/Users/homedir/typesafe/my_app/}my_app...
[info] downloading http://repo.typesafe.com/typesafe/releases/org/slf4j/slf4j-api/1.6.1/slf4j-api-1.6.1.jar ...
[info]  [SUCCESSFUL ] org.slf4j#slf4j-api;1.6.1!slf4j-api.jar (1481ms)

Reading this lead me to doing the task before pushing/resolving.
