sbt equivalent of gradle's JavaExec

Question

Is there an equivalent of gradle's JavaExec task in sbt? Here's an example from the docs to understand what I'm looking for:

apply plugin: 'java'

task runApp(type: JavaExec) {
  classpath = sourceSets.main.runtimeClasspath

  main = 'package.Main'

  // arguments to pass to the application
  args 'appArg1'
}

I need to configure classpath, main and pass some args - as in this example.

Answer 1

runner seems to be similar to gradle's JavaExec, for example

val runApp = taskKey[Unit]("sbt equivalent of gradle's JavaExec")
runApp := {
  (runner in Compile).value.run(
    mainClass = "example.Main",
    classpath = (fullClasspath in Runtime).value.files,
    options = Array("appArg1"),
    log = streams.value.log
  )
}
