Question: The configured repo MUST be a maven repo, but was: FileRepository

[felixoi]

I'm currently trying to refactor a project from play 2.5 to play 2.6. Therefore I want to upgrade aether-deploy from 0.17 to 0.20

The config for 0.17 was this one:

publishTo <<= version { (v: String) =>
  val repoName = sys.props.get("repo.name")
  val repoUrl = sys.props.get("repo.url")
  if (repoName.isDefined && repoUrl.isDefined)
    Some(repoName.get at repoUrl.get)
  else
    Some(Resolver.file("file", new File(Path.userHome.absolutePath + "/.ivy2/local")))
}

For 0.20 I refactored it to be:

publishTo := {
  val repoName = sys.props.get("repo.name")
  val repoUrl = sys.props.get("repo.url")
  if (repoName.isDefined && repoUrl.isDefined) {
    Some(repoName.get at repoUrl.get)
  } else {
    Some(Opts.resolver.mavenLocalFile)
  }
}

But it creates a error when setting no system properties: The configured repo MUST be a maven repo, but was: FileRepository
