How can I run compile and run Scala code programmatically

I have the following code and I would like to compile it on the fly and run it.

object HelloWorld {
  def main(args: Array[String]): Unit = {
    println("Hello, world!")
  }
}

So far I have tried something like below:

import scala.reflect.runtime.currentMirror
import scala.tools.reflect.ToolBox

object MainScala {
  def main(args: Array[String]): Unit = {
    val toolbox = currentMirror.mkToolBox()
    val source =
      """
        |object HelloWorld {
        |  def main(args: Array[String]): Unit = {
        |    println("Hello, world!")
        |  }
        |}
        |""".stripMargin
    val tree = toolbox.parse(source)
    val binary = toolbox.compile(tree)
    var c = binary.getClass
    val m = c.getMethod("main", classOf[Array[String]])
    val params = Array("Apple", "Banana", "Orange")
    m.invoke(null, null)
  }
}

After toolbox.compile(tree) I am not able to get the Class object of the compiled code.
