Set up sbt to fetch dependency for another version of Scala than the project's?

Question

My project uses Scala 2.9.3, and I want to use Spire for 2.9.2. What do I specify in my sbt build file to get Spire for 2.9.2?

I tried

"org.spire-math" %% "spire" % "0.6.0"

but it fails looking for Scala 2.9.3.

What version of sbt are you using? – Seth Tisue Oct 26 '13 at 12:21 — Seth Tisue, Oct 26 '13 at 12:21

One has to append the corresponding library name with an underscore and required scala version and verify the appropriate version number of the library(in my case, 0.3.0)

"org.spire-math" % "spire_2.9.2" % "0.3.0"

`%%` appends the Scala version number, so if you are manually appending it yourself already as in your example, then you want just `%` not `%%`. – Seth Tisue Oct 26 '13 at 12:22
