切换播放2.1/sbt的“实验性”

Question

我需要为我的Play 2.1-snapshot使用Akka 2.1 (因为2.1已经被转换为scala.concurrent.Future，而不是来自Akka的旧的Future，所以我认为我将需要使用Akka 2.1的akka.pattern.Patterns.ask )。但是，Play 2.1-snapshot默认配置为2.0.2：

+-------------------------------------------------------------------+---------------------------------------------------------+---------------------------------------------+
| com.typesafe.akka:akka-actor:2.0.2                                | com.github.scala-incubator.io:scala-io-core_2.9.2:0.4.1 | As akka-actor-2.0.2.jar                     |
|                                                                   | com.typesafe.akka:akka-slf4j:2.0.2                      |                                             |
|                                                                   | play:play_2.9.2:2.1-SNAPSHOT                            |                                             |
|                                                                   | play:akka-sip14-adapters_2.9.2:2.1-SNAPSHOT             |                                             |
+-------------------------------------------------------------------+---------------------------------------------------------+---------------------------------------------+

在Play/project/Build.scala中

"com.typesafe.akka"                 %    (if(experimental) "akka-   actor_2.10.0-M7" else "akka-actor" ) % (if(experimental) "2.1-M2" else "2.0.2"),
"com.typesafe.akka"                 %    (if(experimental) "akka-   slf4j_2.10.0-M7" else "akka-slf4j" ) % (if(experimental) "2.1-M2" else "2.0.2"),

如何打开Play 2.1的实验功能？

谢谢

您必须自己构建播放快照，并在启动sbt时使用experimental系统属性设置为true：

-Dexperimental=true
