How to run playframework sample in Intelllij 13?

Question

I am using Intellij 13 Ultimate and want to create a Play Framework sample. But I am unable to build this project because it always throws this error:

object index is not a member of package views.html
Ok(views.html.index("Your new application is ready."))

I have tried this on both Mac and Windows platforms, but the error is always the same.

How can I solve this?

Answer 1

The generation works just fine and all the paths are correctly added to the build. However the routes are not (yet) compiled by the plugins (scala+playframework), thus the reverse routing classes generated by play are not available for intellij. You will have the same problem with the templates.

If you run a play compile (or a sbt compile), the classes will be generated and intellij should be able to pick them up and compile your project.

Answer 2

I found a trick here.

If you generate the play-scala project using activator command line activator [new my_first_project play-scala]. You'll get the following sbt build file.

name := """my_first_project"""

version := "1.0-SNAPSHOT"

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

scalaVersion := "2.11.7"

libraryDependencies ++= Seq(
  jdbc,
  cache,
  ws,
  "org.scalatestplus.play" %% "scalatestplus-play" % "1.5.1" % Test
)

resolvers += "scalaz-bintray" at "http://dl.bintray.com/scalaz/releases"

But IF you create a project from intellj using NewProject->Scala-Play 2.x, you will get the following sbt.

name := "my_second_project"

version := "1.0"

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

scalaVersion := "2.11.7"

libraryDependencies ++= Seq( jdbc , cache , ws   , specs2 % Test )

unmanagedResourceDirectories in Test <+=  baseDirectory ( _ /"target/web/public/test" )  

resolvers += "scalaz-bintray" at "https://dl.bintray.com/scalaz/releases"  

fork in run := false

after combine them. Ignore the name. And I set for in run to false

name := "my_second_project"

version := "1.0"

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

scalaVersion := "2.11.7"

libraryDependencies ++= Seq( jdbc , cache , ws   , specs2 % Test )

unmanagedResourceDirectories in Test <+=  baseDirectory ( _ /"target/web/public/test" )  

resolvers += "scalaz-bintray" at "https://dl.bintray.com/scalaz/releases"  

fork in run := false

After doing that. Open the activator-generated project with Intellj, configure a run with Play 2.x run. Everything goes well.

By the way, if you open the activator-generated project before you change the sbt file. You might need to rm -r .idea

Hope that helps.
