Scala -- not a member of package

I am learning Scala so bear with me if this is a stupid question.

I have this package and a class (teared it down to most simplistic version):

package Foo {
  class Bar {}
}

then in main.scala file I have:

import Foo.Bar

object test {
  def main() {
    val b = new Bar()
  }
}

Why am I getting this:

test.scala:1: error: Bar is not a member of Foo

It points at the import statement.

The most likely explanation is that you did not compile the first file, or you are doing something wrong when compiling. Let's say both files are in the current directory, then this should work:

scalac *.scala

It should generate some class files in the current directory, as well as a Bar.class file in the Foo directory, which it will create.

scalac is the scala compiler. Foo.bar needs to have been compiled for you to use it, so you can't just run your main.scala as a script.

The other mistake in your code is that the main method needs to be 

def main(args: Array[String]) {  ...

(or you could have test extends App instead and do away with the main method).

I can confirm if you put the two files above in an empty directory (with the correction on the main method signature) and run scalac * followed by scala test it runs correctly.
