sbt compile: varios errores "object is not a member of package views.html" - scala, sbt, playframework-2.0

Intento crear un proyecto de Scala basado en el marco Reproducir utilizando el sbt. Cuando intento ejecutar "compilación de sbt" desde mi terminal obtengo varios errores de compilación como el siguiente:

[error] <project.dir>/app/controllers/Application.scala:229:
object database is not a member of package views.html
[error]     Ok(views.html.database(t2, JsonHelpers.TotalTip.langsForm))
[error]                   ^

Este es mi archivo build.sbt:

import play.sbt.PlayImport._
import com.typesafe.sbt.less.Import.LessKeys

name := """<app_name>"""
lazy val root = (project in file("."))
.enablePlugins(PlayScala)
.enablePlugins(GatlingPlugin)
.enablePlugins(BuildInfoPlugin, GitVersioning, GitBranchPrompt)
.settings(
buildInfoKeys := Seq[BuildInfoKey](name, version, scalaVersion, sbtVersion),
buildInfoPackage := "app")

¿Es un problema de dependencias? ¿Alguien tiene una idea de por qué recibo estos errores?

Gracias
