Playframework 从2.0.4到2.1.1的播放迁移，sbt错误

当我试图从play 2.0.4升级到play 2.1.1时，我似乎一直遇到问题。我遵循了迁移指南上的所有内容。首先，它一直在抱怨我的代理人。我想当我运行play clean时，我最终通过添加-DhttpProxyHost、User等来解决这个问题。现在我遇到了这个问题。我发现一些人有类似的问题，但我认为没有一个明确的解决方案来解决这个问题。任何帮助都将不胜感激

您还需要安装Play2.1并使用它来启动您的项目。目前，您正在运行使用Scala 2.9的2.0.2，而Play 2.1仅适用于Scala 2.10

sbt 0.12.2似乎只适用于Scala 2.9.2，而不是2.9.1
