How to set dependency as runtime in SBT (to mimic runtime scope in Maven)?

Question

I have a dependency in runtime scope in a Maven project:

<dependency>
  <groupId>org.docbook</groupId>
  <artifactId>docbook-xml</artifactId>
  <version>4.4</version>
  <scope>runtime</scope>
</dependency>

How can I express this in SBT?

Answer 1

You should use runtime configuration for the dependency in build.sbt as follows:

libraryDependencies += "org.docbook" % "docbook-xml" % "4.4" % "runtime"

With this, classpath should be properly set - show managedClasspath for compile and runtime configurations to verify it:

[sbt-13-0-1]> help dependencyClasspath
The classpath consisting of internal and external, managed and unmanaged dependencies.
[sbt-13-0-1]> show managedClasspath
