Answer 1

@som-snytt solution worked for me on a clean sbt project. It didn't work on an akka-http project. this is the manual solution I've found (hardcoded path. One should adjust it to his env or put it in conf file)

It is just telling the compiler where to find scala libs for compilation

    val settings = new Settings()
    //didn't need this one:// settings.embeddedDefaults[Probe]
    settings.classpath.value = "/home/oz/.ivy2/cache/org.scala-lang/scala-compiler/jars/scala-compiler-2.11.8.jar:/home/oz/.ivy2/cache/org.scala-lang/scala-library/jars/scala-library-2.11.8.jar:/home/oz/.ivy2/cache/org.scala-lang/scala-reflect/jars/scala-reflect-2.11.8.jar:/home/oz/.ivy2/cache/org.scala-lang.modules/scala-xml_2.11/bundles/scala-xml_2.11-1.0.4.jar:/home/oz/.ivy2/cache/org.scala-lang.modules/scala-parser-combinators_2.11/bundles/scala-parser-combinators_2.11-1.0.4.jar"
    settings.bootclasspath append "/home/oz/.ivy2/cache/org.scala-lang/scala-library/jars/scala-library-2.11.8.jar:/home/oz/.ivy2/cache/org.scala-lang/scala-compiler/jars/scala-compiler-2.11.8.jar:/home/oz/.ivy2/cache/org.scala-lang/scala-reflect/jars/scala-reflect-2.11.8.jar:/home/oz/.ivy2/cache/org.scala-lang.modules/scala-xml_2.11/bundles/scala-xml_2.11-1.0.4.jar:/home/oz/.ivy2/cache/org.scala-lang.modules/scala-parser-combinators_2.11/bundles/scala-parser-combinators_2.11-1.0.4.jar:/home/oz/.ivy2/cache/jline/jline/jars/jline-2.12.1.jar"
