Build.scala:指定scala版本无效

我使用playframework，下面是我在Build.scala中的appDependencies：

  val appDependencies = Seq(
// Add your project dependencies here,
jdbc,
anorm,
"com.rabbitmq" % "amqp-client" % "3.0.1",
"com.typesafe.akka" %% "akka-agent" % "2.1.0",
"org.mongodb" %% "casbah" % "2.5.0",
"com.novus" % "salat_2.9.1" % "1.9.1",
"se.radley" % "play-plugins-salat_2.9.1" % "1.1"

)

scala 2.10没有salat和play-salat插件，因此我明确指定了scala版本。但它不起作用：

我遗漏了什么？

Salat 1.9.2-SNAPSHOT适用于2.10。

请允许我承认我的无知：原因是每次修改Build.scala时我都无法运行

play

命令。我唯一尝试过的就是一次又一次地运行。

因为我感觉到您试图将一些根据Scala 2.10编译的Scala库与另一些根据Scala 2.9编译的库混合在一起，所以不要这样做！事实上，如果你不想自取灭亡，千万不要混合使用针对不同Scala主版本编译的库（Scala版本控制方案是era.major.minor，因此2.9和2.10有不同的主版本）。原因是Scala只保证小版本之间的二进制兼容性（无耻的二进制兼容性插件：），谢谢大家的提醒！这个问题仍然很紧迫……似乎不是：（[warn]===Sonatype OSS快照：尝试过[warn][warn]===Sonatype OSS发布：尝试过[warn][warn]===public:triedAaand

java.lang.NoClassDefFoundError:scala/reflect/ClassManifest

尝试在mongodb中插入对象时。正如我们所看到的，该插件使用从scala 2.10中删除的ClassManifest。是的，它不起作用，我得到了相同的ClassManifest错误。
