How to use multiple versions of a library in Scala?

Question

I am using a library say A in Scala which is dependent on version x.11 of another library say Z.

Now, I am also using a library say B which is dependent on version

In sbt, conflicts between libraries are configured using the conflict manager. By default, the latest revision is selected but this can also be overridden in you .sbt file:

conflictManager := ConflictManager.strict

If you're using sbt 0.13.6 or greater you will be warned when you have an incompatible binary version between your dependencies. In this situation, you could configure an override in your sbt file for the specific library:

dependencyOverrides += "org.raman" % "Z" % "x.11"

This will force the resolved version of Z to x.11 but not pull a direct dependency in.
