How to change JDK set by SBT import in IntelliJ IDEA?

Question

When Scala plugin reimports an SBT project in IntelliJ IDEA, it changes the project's JDK to 1.6. Is it a way to choose which JDK version Scala plugin sets during reimport of the STB project.

Answer 1

You can set JDK options like these javacOptions in Compile ++= Seq("-source", "1.7", "-target", "1.7", "-Xlint:unchecked", "-Xlint:deprecation"), etc on SBT level in your project settings. It should help IntelliJ to use correct JDK version.

Answer 2

Running sbt in the following way resolved it for me

sbt -java-home `/usr/libexec/java_home -v 1.7`
