Unable to create Play framework web application using sbt?

Question

I've followed this documentation to create a new Play application, myFirstApp, using sbt. I've a build.sbt in the myFirstApp folder and a plugins.sbt in myFirstApp/project folder.

However, I'm getting the following error on executing sbt from myFirstApp,

~/ScalaWorkspace/myFirstApp/build.sbt:7: error: not found: value playScalaSettings
playScalaSettings
^
[error] Type error in expression
Project loading failed: (r)etry, (q)uit, (l)ast, or (i)gnore? i
[warn] Ignoring load failure: no project loaded.

How do I solve this problem?

UPDATE 1: Getting this error:

Answer 1

That was my first sbt -centric Play development so bear with me if the solution doesn't meet acceptable quality standards.

I followed the section Create a new application without having Play installed in the document Creating a new application and ended up with the following files.

build.sbt is as described in the document.

import play.Project._

name := "My first application"

version := "1.0"

playScalaSettings

I then created project/build.properties as it's a recommended approach to have reproducible builds - the version of sbt is known and fixed.

sbt.version=0.13.0

I modified project/plugins.sbt to be as follows:

// Typesafe snapshots
resolvers += "Typesafe Snapshots" at "http://repo.typesafe.com/typesafe/snapshots/"

resolvers += "Typesafe Releases" at "http://repo.typesafe.com/typesafe/releases/"

// Use the Play sbt plugin for Play projects
addSbtPlugin("com.typesafe.play" % "sbt-plugin" % "2.2.0-RC2")

With the files in the project, I could execute sbt and have the project's prompt.

jacek:~/sandbox/myFirstApp
$ sbt
[info] Loading global plugins from /Users/jacek/.sbt/0.13/plugins
[info] Loading project definition from /Users/jacek/sandbox/myFirstApp/project
[info] Set current project to My first application (in build file:/Users/jacek/sandbox/myFirstApp/)
[My first application] $ run
...lots of [SUCCESSFUL ]'s
