And for those working in Scala and building with Maven still, I second the recommendation to download & run Ivy, turn on the useZincCompiler option in maven-scala-plugin's configuration, and enjoy substantially faster build times (and automatically falling back to a normal build if Zinc isn't running). You don't even need to specify a scala home directory for Zinc like it claims; scala-maven-plugin will tell Zinc to use the Scala libs from your Maven repo.
I like this a lot. Setting up your own Maven repository on your own server, that can be internal or whatever, can be as simple as setting up a server that serves static files and the publishing itself is just copying files by means of SFTP or whatever. The protocol for finding all the listed dependencies on that server is also simple, so in case of problems you can usually understand what's going on.
This is much saner than the alternatives I've encountered on other platforms.
