所以这不起作用（404）：http://repo1.maven.org/maven2/com/typesafe/akka/akka-actor/2.1.2/akka-actor-2.1.2.pom

但这确实有效：http://repo1.maven.org/maven2/com/typesafe/akka/akka-actor_2.10/2.1.2/akka-actor_2.10-2.1.2.pom

查看g8模板（line 16）：

"com.typesafe.akka" % "akka-actor"      % "$akka_version$",

我猜您需要修改project/Build.scala，以便说明：

"com.typesafe.akka" % "akka-actor_2.10"      % "2.1.2",

如果有效，请告诉我。
