I'm pretty skeptical of this. Do we really need this in the main repo?

[jcoveney]

Isn't this something people can add to their own sbt or ivy configurations?

[gerashegalov]

@johnynek it's useful for quick iterations working on a dependency to avoid poluting a central repo with unnecessary builds.

@jcoveney If this can be achieved with a simple config, I am all for it. I am new to sbt.

[gerashegalov]

@jcoveney according to http://www.scala-sbt.org/release/tutorial/Library-Dependencies.html and other forums I found by googling that's actually the way to do it with sbt.

I think there are no real reservations against this change because this is just a normal way you would expect to share artifacts via maven locally when working on multiple projects.

[julienledem]

This looks reasonable to me. This is what maven does by default allowing for local deployment (install) of artifacts. This makes working on cross project changes easier.
@johnynek Does SBT have a default mechanism for a local repo? any strong opinion against this?

[ianoc]

Sbt by default uses ivy for a local repo which is why we haven't seen this before. When installing artifacts for local usage we install them into both the maven and ivy repos in our usual flow between our OSS repos. A pure maven repo rather than SBT would probably find this more difficult. If there are no objections I'll merge this later as a harmless parity level thing between .ivy and .m2
