set retrieve := true to have dependencies retrieved to the build the location is by default shared by all projects in a build (<built-root>/lib_managed/), but can be per-project update-classifiers and update-sbt-classifiers retrieves artifacts with classifiers for project dependencies and for sbt, respectively The default setting is classifiers := Seq("javadoc", "sources")
the information included is: configuration -> module -> artifact -> file
- rename resolvers to fullResolvers, baseResolvers to resolvers - if set, use javaHome for compilation as well as running - add scalaHome configuration for easily configuring scalaInstance for a local Scala installation - no longer require source roots for Java sources. Instead, resolve ambiguities by package name and then distance to root. Common package suffixes in different directories within the same project are a potential problem.
