Running HelloWorld fails...

Hello everybody,

I installed the Eclipse-Scala plugin on my Fedora 11 and tried the
HelloWorld example, but it doesn't work at all.


The problems are that the simple HelloWorld script:


       package hello

       object HelloWorld extends Application {
         println("Hello world!");

       }

contains syntax errors:

line 1: Syntax error on tokens, ClassHeaderName expected instead
line 4: Syntax error on token ""Hello world!"", delete this token

The crazy thing is, that the errors are of type "Java Problem"...
Furthermore nearly everything is underlined with red curley lines.
It's really a scala project and a scala source file.

When I run this as scala application I get a popup:

       "Launch Error"
Selection does not contin a main type

The details of my system are:

$ uname -a
Linux smallfish 2.6.29.5-191.fc11.x86_64 #1 SMP Tue Jun 16 23:23:21 EDT
2009 x86_64 x86_64 x86_64 GNU/Linux


Fedora Eclipse Platform
Version: 3.4.2
Based on build id:  20090211-1700

scala plugin:
2.7.5.final

Does anyone have an idea?

Best Regards
Udo
