How to use multiple versions of a library in Scala?

Question

I am using a library, say A in Scala, which depends on the x.11 version of another library, say Z.

Now I also use a library that says B, which depends on version x.31 of Z.

This leads to a compilation error, because we will have two versions of the Z library, how can I use both the A and B libraries in Scala sbt? Is there any way to specify it.

Answer 1

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

conflictManager := ConflictManager.strict

sbt 0.13.6 , , . sbt :

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

Z x.11, .
