NewPerson question: NoClassDefFoundError: scala/Serializable
Based on a github download built in Eclipse.
The jars, based on building with maven, include Scala 2.8.1 in which
the class is serializable.scala, lower case. If I upgrade to the
latest Scala, which has Serializable.scala in its code, then other
APIs break.
The failure appears to start on line 66 in boot.scala (stack trace below)
The maven build, dropped into Jetty, runs fine. The same code dropped
into Eclipse and built does not boot.
What am I missing?
Thanks
Jack

Hi Jack!
Apache ESME hasn't YET supported Scala 2.9.x version. ESME is based on Lift
web framework, current stable Lift release version is 2.3 which in turn
based on Scala 2.8.1. Support for Scala 2.9.x has been already added to the
Lift 2.4 Milestone 1, so we will upgrade to Lift 2.4 version when stable
release is available.
Best Regards,
Vladimir
