NewApplication

Creating a new application

Once the Play is correctly installed, you can create a new application.

Create a new application with the play script.

The easiest way to create a new application is to use the play new command.

$ play new myFirstApp

It will ask a few question:

• The application name (just for information, this name will be used later in several messages).
• The template to use for this new application. You can choose over a default Scala application, a default Java application, or an empty application.

Note that choosing a template at this point does not imply that you can't change of main language later. You can create a new application using the default Java application template and start adding some Scala code later.

Once the application is created you can use the play command again to enter the Play 2.0 console.

$ cd myFirstApp
$ play

Create a new application without having Play installed.

You can also create a new Play application without installing Play, using sbt.

First install sbt 0.11.0.

Then create a new directory for your new application, and configure your sbt build script, by adding:

In project/plugins.sbt:

resolvers ++= Seq(
  "Maven Repository" at "http://repo1.maven.org/maven2/",
  "Typesafe Repository" at "http://repo.typesafe.com/typesafe/releases/"
)

libraryDependencies += "play" %% "play" % "2.0-beta"

In project/Build.scala:

import sbt._
import Keys._
 
object ApplicationBuild extends Build {
 
  val appName         = "My first application"
  val appVersion      = "1.0"
 
  val appDependencies = Nil
 
  val main = PlayProject(appName, appVersion, appDependencies)
 
}

You can then launch the sbt console in this directory:

$ cd myFirstApp
$ sbt

sbt will load your project and fetch every dependencies.
