Problem, scala.collection.immutable.Set$Set1 cannot be cast to scala.collection.generic.Addable

[Banduk]

Hi guys,

I doin't even know if this mail list stills being visited, but here's
my problem!
I'm new with scardf and I'm having some problems with the basic
examples. I think it's some incompatibility with the scala 2.9.1
library
This is my output for the basic example explained at
http://code.google.com/p/scardf/wiki/ReplGuide
Could you try to help me?

dc: org.scardf.Vocabulary = Vocabulary(http://purl.org/dc/elements/1.1/

scala> val homepage = UriRef( "http://www.example.org/index.html" )
homepage: org.scardf.UriRef = <http://www.example.org/index.html>

scala> :paste

Hi Banduk,

I cannot replicate your error on Scala 2.9.1, Java 1.6.0. Try "mvn
scala:console" and copy code without using the paste mode.

Cheers,
Hrvoje

Hi, thanks for the quick answer,

Actually I can't even build using "scala:console".

It looks like you have a problem with maven.

Try a fresh installation of maven 2.2.1. Try running it with the "-e"
switch to get more debug info.

Hi,

So I really had a problem with maven. I had a small quota on my user. I moved the .mé repository to a local path and maven works fine now!

Thanks

However, I still getting the same error, here my output:

I see you are using the scardf-0.5.jar distrubution. You should try to
build scardf from the SVN trunk (it's 0.6-SNAPSHOT).

Let us know if this fixes your problem.

Hrvoje

[Mauricio Banduk]

Nice, it works!

I was sure I had already tried this!

Just one thing; it wold be nice to prevent people about it changing the phrase at the wiki (http://code.google.com/p/scardf/wiki/ReplGuide)

"Start the interpreter. You will need to add Scardf 0.5-SNAPSHOT (download) and Joda Time 1.6 (download) JARs to the classpath (use the :cpinstruction)."

Thenk you again!

Cheers,

Banduk

[Hrvoje Šimić]

Fixed wiki & uploaded the 0.6-SNAPSHOT.

Thanks for the feedback. If you see any more errors or room for
improvement, please report them here.

Cheers,
Hrvoje

[Mauricio Banduk]

Perfect!

Thank you,

Cheers
