I am trying to complete the exercises at the end of Chapter 2; I need the HelloWorldFigaro example as the starting point, as per the first exercise. I have unzipped the file. According to Appendix A, all I have to do is to navigate to the PracticalProbProg/examples directory and type:

sbt console
sbt "runMain chap01.HelloWorldFigaro"

I have typed every conceivable combination of the above characters and all I see are errors. I have been at this for over an hour and a half with no results. Here is the output:

Welcome to Scala version 2.11.6 (Java HotSpot(TM) Client VM, Java 1.8.0_66).
Type in expressions to have them evaluated.
Type :help for more information.

scala> sbt "runMain chap01.HelloWorldFigaro"
<console>:1: error: ';' expected but string literal found.
sbt "runMain chap01.HelloWorldFigaro"

I have typed this with quotes, without quotes, with package name, without package name, etc., etc., etc., etc., etc.....
Nothing works; there are nothing but errors.
I also tried all of this with Same result; nothing but errors.

What is the problem? Is there some alternative way to get at the HelloWorld example?

Sbt tasks can be run at the console or from the command-line.

If you run from the console (as you have) just type

runMain chap01.HelloWorldFigaro

If you run from the command-line then prefix with sbt, ie:

sbt runMain chap01.HelloWorldFigaro
