NoSuchMethodError with sbt 0.13.9 and Play 2.2.6 and plugin version 4.0.0

Hi,

I have installed the sbteclipse-plugin in ~/.sbt/ as described, but when running sbt eclipse I get the folowing error:

java.lang.NoSuchMethodError: com.typesafe.sbteclipse.core.EclipsePlugin$.EclipseProjectFlavor()Lcom/typesafe/sbteclipse/core/EclipsePlugin$EclipseProjectFlavor$;

[error] java.lang.NoSuchMethodError: com.typesafe.sbteclipse.core.EclipsePlugin$.EclipseProjectFlavor()Lcom/typesafe/sbteclipse/core/EclipsePlugin$EclipseProjectFlavor$;

Start by reproducing sbt eclipse with sbt 0.13.9, Play 2.2.6, and plugin 4.0.0, using the failing build.sbt entry at line 19. Trace the PlayEclipse.scala:123 call to EclipsePlugin$.EclipseProjectFlavor() and verify that the command completes without the reported NoSuchMethodError.
