package object and scala worksheet

Question

I have a strange behaviour in the eclipse IDE.

I reproduced it with the documentation on package objects

• I have a file src/main/scala/gardening/fruits/Fruit.scala containing

  package gardening.fruits

  case class Fruit(name:String)

  object apple extends Fruit("Apple")

  object plum extends Fruit("Plum")

• a file src/main/scala/gardening/fruits/package.scala containing

  package gardening

  package object fruits { val planted = List(apple, plum)
  def showFruit(fruit: Fruit) { println(fruit.name +"s are ") } }

• a scala worksheet in src/main/scala/fruitws.sc containing

  import gardening.fruits._

  object PrintPlanted { def main(args: Array[String]) { for (fruit: Fruit <- fruits.planted) { showFruit(fruit) } } }

Now :

• eclipse says "can't find gardening" (and of course fruits and Fruit)
• if I hit ctrl space after placing a dot after gardening, some autocompletion appears though
• stranger, one of those completion is called gardeningfruits (so as a child of gardening, with no dots...)

What am I doing wrong that prevents the worksheet to execute properly ?

edit

I think the package object idea is not available in worksheet.

As a separate point, worksheet might mandate some file organisation on disk that scala files themselves escape (aka, having a file in gardening/fruit/fruit.scala and package gardening only in the file). Not sure..

You need to compile .scala files before you can import them into worksheet
