"Unexpected end of file from server" error on sbt codeArtifactPublish

[Michael Doo]

Followed the readme to try and publish to CodeArtifact. Getting the error (codeArtifactPublish) java.net.SocketException: Unexpected end of file from server when running the command sbt codeArtifactPublish.

My build.sbt:

lazy val root = (project in file(".")).
  settings(
    name := "testPackage",
    organization := "org.myorg",
    version := "0.1.0-SNAPSHOT",
    versionScheme := Some("semver-spec"),
    scalaVersion := "2.13.6",
    codeArtifactUrl := "https://test-domain-1234567890.d.codeartifact.us-east-1.amazonaws.com/maven/test-repo/"
  )

Console output and stacktrace when running sbt codeArtifactPublish:

I'm sad to say this is likely related to this issue: #8. Specifically, this plugin does not support SNAPSHOT jars at the moment. I've made some progress in addressing this shortcoming, but I just started a new job and so haven't had a ton of time (or energy) to work on it.

My suggestion at the moment is to remove the -SNAPSHOT from your version and see if that fixes it.

[Michael Doo]

Indeed, that's the fix. Thanks!
