I'm trying to do almost exactly what is described in the official sbt documentation, at http://www.scala-sbt.org/0.13.5/docs/Detailed-Topics/Proxy-Repositories.html. I'd like to proxy both maven and ivy packages, and it seems like only Artifactory supports both. I went through the installation and got things roughly working, except that I couldn't point my remote repository (for local caching) at e.g., sbt-plugin-releases because it uses a custom repository layout (including the sbt version), which isn't allowed in the free version of Artifactory.
How do other people do this? It can't be uncommon if there's a whole documentation page on it. Does doing sbt stuff with a proxied ivy repository have to cost me $2750 a year? It's a little frustrating because I don't need most of the Artifactory Pro features, but I don't think I can get by without the custom layouts. Nexus and Archiva only seem to support Maven.
