Scala + stax compile problem during deploy process

Question

Hello. I developed an app in scala-ide (eclipse plugin), no errors or warnings. Now I'm trying to deploy it to the stax cloud:

$ stax deploy

But it fails to compile it:

compile:

ERROR: : The following error occurred while executing this line:

I see two errors, it is complaining about: the first one is FlickrUtils class constructor, which is defined like this:

class FlickrUtils(val userId : String) {
    //...
}

The second one is the fact, that two fields are missing from Photo class, which is:

class Photo (val photoId:String, val userId:String, val secret:String, val server:String) {
    private val _medium1 = "/sizes/m/in/photostream"
    val link = "http://flickr.com/photos/" + userId + "/" + photoId
    val medium1 = link + _medium1
}

Seems like stax sdk uses the wrong comliler (?). How do I make it use the right one? If it is not, what is the problem here, and what are some ways to resolve it?

Edit: $ scala -version says

Scala code runner version 2.8.0.final -- Copyright 2002-2010, LAMP/EPFL

I tried compiling everything with scalac manually, puting everything to their places, and running stax deploy afterwards -- same result.

Answer 1

I actually resolved this by moving FlickrUtils and Photo classes to the packages, where snippets originally are, but I still don't get, why it was not able to compile and use them from the other package.
