插件.sbt


// Scoverage Plugin
addSbtPlugin("org.scoverage" % "sbt-scoverage" % "1.1.0")

// SBT Native Packager
addSbtPlugin("com.typesafe.sbt" %% "sbt-native-packager" % "1.0.2")

// Play Plugin
addSbtPlugin("com.typesafe.play" % "sbt-plugin" % "2.5.0")

// Assembly Plugin
addSbtPlugin("com.eed3si9n" % "sbt-assembly" % "0.11.2")

addSbtPlugin("com.jamesward" % "play-auto-refresh" % "0.0.13")

构建.scala


object TIBuild extends Build {

  import BuildSettings._
  import Dependencies._

  // configure prompt to show current project
  override lazy val settings = super.settings :+ {
    shellPrompt := { s => "[TI PROJECT] " + Project.extract(s).currentProject.id + " > " }
  }

  BrowserNotifierKeys.shouldOpenBrowser := false
  JsEngineKeys.engineType := JsEngineKeys.EngineType.Node

  //... Multi projects description here, nothing significant to this issue ...
}

reference.conf 中的部分配置（应用程序中没有 application.conf）：
```
 
play.server {
  netty {
    transport = "native"
  }
}
```

这个 jar netty-transport-native-epoll-4.0.33.Final-linux-x86_64.jar在 dist 文件的“/lib”文件夹中可用（作为传递依赖项）。

但是，当我在登台服务器（Ubuntu 14.0.4）中运行该应用程序时，出现此错误：
