Implementing a task docs fails

[Lachlan Deck]

Hi there,

the following documentation doesn't appear to work:

http://www.scala-sbt.org/release/docs/Detailed-Topics/Tasks.html

Is there an example project someone has for sbt 0.13 that works?

i.e., defining a build.sbt with the following contents

----------------------------------------------

lazy val hello = taskKey[Unit]("Prints 'Hello World'")

hello := println("hello world!")

----------------------------------------------

build.sbt:3: error: illegal start of simple expression
lazy val hello = taskKey[Unit]("Prints 'Hello World'")
^
[error] Error parsing expression.  Ensure that there are no blank lines within a setting.

thanks

Lachlan

I get "hello world!".

% cat build.sbt 

lazy val hello = taskKey[Unit]("Prints 'Hello World'")

hello := println("hello world!")

% sbt hello
