有没有办法在scala 2.10中获得运行时编译错误的正确报告？

Question

在scala 2.9.x中,我tools.nsc.Global直接将某些字符串编译成一个类并执行它.

在scala 2.10中,可以用以下内容替换它:

import scala.reflect.runtime._;
val cm = universe.runtimeMirror(getClass.getClassLoader)
import scala.tools.reflect.ToolBox;
val tb = cm.mkToolBox()
tb.eval(tb.parse("class C; new C"))

它完美无瑕.唯一的问题是,使用旧的(不推荐的)方法,我可以使用StoreReporter(带有错误消息,行号)获得所有编译失败的非常漂亮的摘要,并且新方法只会在编译错误时引发异常.

有什么方法可以实现这一点吗？

scala> import scala.reflect.runtime._
import scala.reflect.runtime._

scala> val cm = universe.runtimeMirror(getClass.getClassLoader)
cm: reflect.runtime.universe.Mirror = JavaMirror with ...

scala> import scala.tools.reflect.ToolBox
import scala.tools.reflect.ToolBox

scala> val tb = cm.mkToolBox()
tb: scala.tools.reflect.ToolBox[reflect.runtime.universe.type] = scala.tools.reflect.ToolBoxFactory$ToolBoxImpl@712fe0c0

scala> tb.eval(tb.parse("class C; new D"))
scala.tools.reflect.ToolBoxError: reflective compilation has failed:
