JSR223 script engine for Scala.
$> ./gradlew clean build
to generate jsr223-scala\build\libs\jsr223-scala-xx.jar
This Scala script engine wrapper is discoverable under "scalaw" name (http://docs.oracle.com/javase/7/docs/technotes/guides/scripting/programmer_guide/index.html).
User has access from the scala script to predefined variables, according to the current script context. Here are some of them
val result = 123
val loop = 2
val runs = 4
val selected = false
Considering a simple 2-tasks workflow with task_A -> task_B
// In task_A
variables.put("AA", "aa")
variables.put("BB", Array(1, 2, 3))
variables.put("CC", Map("name" -> "Gromit", "likes" -> "cheese", "id" -> "1234"))
val result = Map(0 -> "abc", 1 -> "def")
// In task_B
println(variables.get("AA")) // aa
val arr = variables.get("BB").valueCast[Array[Int]]
println(arr(0)) // 1
println(variables.get("CC").values) // MapLike.DefaultValuesIterable(Gromit, cheese, 1234)
println(variables.get("CC").get("name")) // Some(Gromit)
println(results(0).getValue.get(0)) // Some(abc)
