I've discovered a bug in JBDS/Eclipse.

The application is: https://github.com/escalante/escalante-quickstart/tree/master/standard-helloworld-lift

If I build a war with Maven, it includes all the jars, see: https://dl.dropbox.com/u/6148072/standard-lift-app-Maven.png

If I build the war, it seems to forget the scala-library jar (at least), see: https://dl.dropbox.com/u/6148072/standard-lift-app-JDBS.png

Of course, without the scala-library jar, the application fails to deploy when deployed via JDBS.

Note: This is a JDBS instance installed with Scala 2.9 IDE, and the IDE correctly identifies the project being a Scala project.
