在Eclipse中玩2.1应用程序作为scala项目（而不是java项目）

如何配置playframework-2.1应用程序build.scala文件来生成一个带有scalanature而不是javanature的eclipse项目？在Eclipse中玩2.1应用程序作为scala项目（而不是java项目）

我发现这个代码（https://github.com/playframework/playframework/blob/2.1.x/framework/src/sbt-plugin/src/main/scala/play/Project.scala）

val mainLang = if (dependencies.contains(javaCore)) JAVA else SCALA

这表明，如果我在相关性具有的javacore我会得到一个Java项目。我试图删除javaCore上的依赖关系，但我有编译错误。

有什么建议吗？

我好不容易才能够配置一个playframework项目中使用Java和Scala源

产生Scala的性质Eclipse项目

使用playframework - 2.1正常编译在Eclipse

是

脚本如下

import sbt._ 
import Keys._ 
import play.Project._ 

object ApplicationBuild extends Build { 

    val appName   = "darzaar" 
    val appVersion  = "1.0-SNAPSHOT" 
    //play.Project.playScalaSettings - is available only in playframework-2.2.x 
    val appDependencies = Seq(
     // added instead of javaCore 
     "play" %% "play-java"  % "2.1.5", 
     "be.objectify" %% "deadbolt-java"  % "2.1-RC2", 
     "be.objectify" %% "deadbolt-scala"  % "2.1-RC2", 
     // Comment this for local development of the Play Authentication core 
     "com.feth"  %% "play-authenticate" % "0.3.4-SNAPSHOT", 
     "postgresql" % "postgresql"  % "9.1-901-1.jdbc4", 
     //javaCore, - commented to keep SCALA nature in eclipse 
     //javaJdbc, 
     jdbc, 
     javaEbean 
    ) 

    import com.typesafe.sbteclipse.core.EclipsePlugin._ 

    val main = play.Project(appName, appVersion, appDependencies) 
     //.settings(play.Project.playScalaSettings:_*) 
     .settings(
     resolvers += Resolver.url("Objectify Play Repository (release)", url("http://schaloner.github.com/releases/"))(Resolver.ivyStylePatterns), 
     resolvers += Resolver.url("Objectify Play Repository (snapshot)", url("http://schaloner.github.com/snapshots/"))(Resolver.ivyStylePatterns), 

     resolvers += Resolver.url("play-easymail (release)", url("http://joscha.github.com/play-easymail/repo/releases/"))(Resolver.ivyStylePatterns), 
     resolvers += Resolver.url("play-easymail (snapshot)", url("http://joscha.github.com/play-easymail/repo/snapshots/"))(Resolver.ivyStylePatterns), 

     resolvers += Resolver.url("play-authenticate (release)", url("http://joscha.github.com/play-authenticate/repo/releases/"))(Resolver.ivyStylePatterns), 
     resolvers += Resolver.url("play-authenticate (snapshot)", url("http://joscha.github.com/play-authenticate/repo/snapshots/"))(Resolver.ivyStylePatterns) 

     // These keys wheren't used by sbt-eclipse when used in playframework 
     //,EclipseKeys.projectFlavor := EclipseProjectFlavor.Scala 
     //,PlayEclipse.mainLang := SCALA 
    ) 
// Uncomment this for local development of the Play Authenticate core: 
// .dependsOn(playAuthenticate).aggregate(playAuthenticate) 

}

我还需要添加一些模板以下进口自defaultScalaTemplatesImport在https://github.com/playframework/playframework/blob/b4006e9dbecaca6f8257a209f7d0fdc6e0345b48/framework/src/sbt-plugin/src/main/scala/PlayKeys.scala

@import play.mvc.Http.Context.Implicit._ 
@import scala.collection.JavaConversions._ 
@import scala.collection.JavaConverters._

从defaultJavaTemplatesImport不同添加以下SBT eclipse插件在plugins.sbt

addSbtPlugin("com.typesafe.sbteclipse" % "sbteclipse-plugin" % "2.3.0")

从播放控制台输入“eclipse”并按回车。

看看SBTEclipse plugin。我看到你已经在使用最新版本的Play。我可以建议你尝试从类型安全的'激活'。
