I use this plugin instead to deploy: addSbtPlugin("no.arktekk.sbt" % "aether-deploy" % "0.28.0")

Same info as above with credentials and resolvers and publishTo entries

sbt aetherDeploy -Dmaven.resolver.transport=wagon -Dhttps.protocols=TLSv1.2

Supposedly they updated CodeArtifact but this has continued to work so I leave well enough alone here.
