SBT native packager: reference to undefined setting Universal / mappings

joesan commented 2 years ago

Expected behaviour

Adding a file under a folder location gets added to the Docker destination directory:

Universal / mappings += (file("data/housing.tgz"), "/opt/docker/data/housing.tgz")

Actual behaviour

@joesan Did you add this .enablePlugins(UniversalPlugin) or that .enablePlugins(JavaAppPackaging) somewhere in your build.sbt file?

I solved it. The problem was that I was specifying the mapping outside of .settings(......). As soon as I had it added inside the .settings(......), it kind of worked.
