Use SBT offline with file based repository

Question

I need to use sbt in an offline environment, but I can stage all of the necessary jars on the filesystem as a local repository. How do I define ~/.sbt/repositories so that it will check the local filesystem for the jars that sbt (and my project) needs? For bonus points, what's the easiest way to set up the local file based repository?

Answer 1

It is all explained at http://www.scala-sbt.org/release/docs/Detailed-Topics/Proxy-Repositories.html

In a nutshell you have to put this into ~/.sbt/repositories

[repositories]
  local
  sharedRepo: file:///path/to/my/shared/repo/.m2/repository

and invoke sbt (or play/activator) with -Dsbt.override.build.repos=true

This will make sure that only local and shared repository is used for resolving dependencies.

The easiest way to make sure that local repository contains the jars you need is to delete the ~/.sbt/repositories file and do an sbt update on the project while online (without the -Dsbt.override.build.repos=true parameter). After that restore the ~/.sbt/repositories file and all resolving will be done from your local repository only.

For setting up a private repository look at artifactory, it has an open source version that is enough for a maven repository.
