How to change Scala version for build definition?

Question

I\'m developing a simple SBT project that includes InputTasks for benchmarking Scala Parallel collections.

I have defined the InputKeys and started writing the tasks

Answer 1

scalaVersion only impacts the version of Scala used to compile the "actual" source code (usually located in src/...). Your error comes from a part of the build definition (under project/), which is always compiled with the Scala version that sbt was built with.
