Hello, my name is 谢威武, you can call me jack.
When I use the SBT commands to compile the project to the error:

error sbt.ResolveException: unresolved dependency: com.typesafe.akka#akka-actor_2.10;2.4-SNAPSHOT: not found
[error] unresolved dependency: com.typesafe.akka#akka-slf4j_2.10;2.4-SNAPSHOT: not found

I just started to contact Scala and Sbt.
I query to your open source project, want to compile, but appeared the mistake, is very upset.
Can you give me a help?I really need!Thank you very much!
