I have a multi-project containing a few subprojects.
The root project's project/build.properties contains
sbt.version=0.13.0
It turned out that one of the subprojects works only with the version 0.12.4 due to a dependency issue.
I put build.properties with that version into its directory but it didn't change the version of sbt for this project.
How do I do that properly? Is it possible at all?
