scala - IntelliJ 和 Play 框架

Question

IntelliJ claims使用 Play 框架。我无法让它工作。

安装 IDEA 14.0

安装 Scala 插件 1.1.1

在 IntelliJ 中打开项目目录

导入为 SBT

导入后，我看不到我的源文件。



我的准系统 Play 项目:

build.sbt

name := "foo"

version := "1.0-SNAPSHOT"

libraryDependencies ++= Seq(
  jdbc,
  anorm,
  cache
)

lazy val root = (project in file(".")).enablePlugins(PlayScala)

项目/plugins.sbt

addSbtPlugin("com.typesafe.play" % "sbt-plugin" % "2.3.4")

配置/路由

GET / controllers.Application.index()

应用程序/ Controller /Application.scala

package controllers
import play.api.mvc._
object Application extends Controller {
  def index = Action {
    Ok("It works!")
  }
}

此过程适用于基本 SBT 项目，但不适用于 Play 项目。

编辑:这些是我来自该 session 的日志:

这是一个提交的错误 here并跟踪 here .

解决方案是使用夜间构建:https://confluence.jetbrains.com/display/SCA/Scala+Plugin+Nightly+Builds+for+Cassiopeia

你可以

手动下载并添加到IDEA的插件目录

或在 IDEA 中添加 http://www.jetbrains.com/idea/plugins/scala-nightly-cassiopeia.xml存储库并安装 scala-intellij-bin。
