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")
- 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.
