scala.reflect.internal.MissingRequirementError

[smatt]

Hi 

I have a project that has a dependency on play-json standalone (see https://github.com/mandubian/play-json-alone).

By adding this dependency i get the following compile error:

[ERROR] error: scala.reflect.internal.MissingRequirementError: object scala.runtime in compiler mirror not found.

To note, play-json-alone has a dependency on scala-reflect. 

Adding this dependency in an sbt project works ok - it compiles and runs without problems the example code provided in the play-json-alone wiki.  

Has anyone else come across this issue?

Regards

Steve
