为什么构建中断与Akka 2.4-快照丢失？

Question

我的build.sbt里有这个

libraryDependencies += "com.typesafe.akka" %% "akka-actor" % "2.4-SNAPSHOT"

libraryDependencies += "com.typesafe.akka" %% "akka-slf4j" % "2.4-SNAPSHOT"

当我编译它时，它说：

::::::::::::::::::::::::::::::::::::::::::::::
[warn]  ::          UNRESOLVED DEPENDENCIES         ::
[warn]  ::::::::::::::::::::::::::::::::::::::::::::::
[warn]  :: com.typesafe.akka#akka-actor_2.10;2.4-SNAPSHOT: not found
[warn]  :: com.typesafe.akka#akka-slf4j_2.10;2.4-SNAPSHOT: not found
[warn]  ::::::::::::::::::::::::::::::::::::::::::::::

为什么会这样呢？即使在这里，http://doc.akka.io/docs/akka/snapshot/intro/getting-started.html也说它必须存在。

在其目录中

sbt-版本信息0.12.1

在我的主用户目录中：

$ sbt sbt-version
[info] Set current project to alex (in build file:/Users/alex/)
[info] 0.13.7

即使在这个sbt.version=0.12.4之后，错误仍然存在。

// name := "my_name123"

version := "0.1"

//scalaVersion := "2.10.4"

unmanagedResourceDirectories in Compile <+= baseDirectory( _ / "src" / "main" / "scala" )

unmanagedResourceDirectories in Compile <+= baseDirectory( _ / "src" / "main" / "java" )

libraryDependencies += "org.scalatest" %% "scalatest" % "2.2.0" % "test"

还必须将Akka快照解析器添加到build.sbt中。

resolvers += "Akka Snapshot Repository" at "http://repo.akka.io/snapshots/"
