Until recently, Jackson core and databind did not publish snapshot version so you had to download the code and compile it yourself. That change recently, so I've just pushed a change that tells SBT where to find the snapshots.

Pardon my question and my infringement on your time. I really want to use the jackson-scala-module, but I can't even get the initialization to run. With the following simple code:

import com.fasterxml.jackson.databind.ObjectMapper
import com.fasterxml.jackson.module.scala.DefaultScalaModule

object TestJSON extends App {
val mapper = new ObjectMapper()
mapper.registerModule(DefaultScalaModule)
}

I get the following error:

I am using scala 2.10.0 to compile everything (including the jack-sacla-module) and the jars listed in the build.sbt file for the jackson library. I am also using Java 7. Am I running unto some Java incompatibility? I'm pretty new to Scala and very new to jackson..in case that doens't show already. :)

If you can help, great. If not, I appreciate your efforts nonetheless. Thanks for contributing.

As far as I know, Scala is still unsupported on Java 7. If you still have this issue on Java 6 then I can take a further look at your use case.

Unfortunately my project also needs Java FX 2.0 and ScalaFX, and I don't believe JavaFX is available for all platforms in Java 6. It's fine...I'll try something else. Thanks for your help.

FWIW, I might be wrong about Scala's support for Java 7, I have just never tested it. But since Java 6 is hitting end of life this month, I'll look more closely to see if it's failure is due to my code or Scala's.
