Scala issues with fromJson

[denisbetsi]

the Scala sample pages is filled with errors

For example
import com.owlike.genson.defaultGenson_
is missing a . to be
import com.owlike.genson.defaultGenson._
This example

 // {"name":"foo bar","age":28,"address":{"street":"rue des lapins",building:1337}}
    val json = toJson(Person("foo bar", 28, Some(Address("rue des lapins", 1337)))

    // {"name":"foo bar","age":28,"address":null}
    val jsonWithNoAddress = toJson(Person("foo bar", 28, None)

    val person = fromJson[Person](json)

Missing ) brackets to close on both val json = and val jsonWIthNoAddress line.

Even after fixing the errors attempting to run the example above with the 2 case classes. Just throws an error

[EugenCepoi]

Thanks for reporting the typos.
What scala version are you using? What genson version are you using?
Looks like a version mismatch between the scala version you are using and the scala version for which genson has been built.

[denisbetsi]

Scala "2.11.7" and latest Genson

[EugenCepoi]

Are you sure you are using the genson build for scala 2.11 and not scala 2.10?
http://mvnrepository.com/artifact/com.owlike/genson-scala_2.11/1.4,
if you are using sbt it would become libraryDependencies += "com.owlike" % "genson-scala_2.11" % "1.4" or libraryDependencies += "com.owlike" %% "genson-scala" % "1.4" to let sbt automatically pick the correct version.

My project is on 2.11.7 I am not sure what it was. due to time crunch I had to use json4s-jackson so I can't verify what it was. :( I'll close this issue.
