val localSbtFile = file("local.sbt")
lazy val rootSettingSets =
Seq(sbt.AddSettings.allDefaults) ++ (
if (localSbtFile.exists)
Seq(sbt.AddSettings.sbtFiles(localSbtFile))
else
Seq.empty
)
and then
lazy val opal = Project(
id = "OPAL" [...]
)
.settingSets(rootSettingSets:_*)
interessting-why does it work? do we have to make changes to local.sbt? (aren‘t the settings just merged?)
