Setting target JVM in SBT

Question

How can I set target JVM version in SBT? In Maven (with maven-scala-plugin) it can be done as follows:

<plugin>
...
    <configuration>
      <scalaVersion>${scala.version}</scalaVersion>
      <args>
         <arg>-target:jvm-1.5</arg>
      </args>
    </configuration>
</plugin>

Answer 1

You can specify compiler options in the project definition:

javacOptions ++= Seq("-source", "1.8", "-target", "1.8") 

Answer 2

As suggested by others in comments, the current sbt version (1.0, 0.13.15) uses the following notation for setting source and target JVMs.

javacOptions ++= Seq("-source", "1.8", "-target", "1.8")
