Scala 运行时记录器异常与dotty

我的项目依赖于scala日志库，我正在尝试升级我的项目以使用dotty。 为此，我从中克隆了示例dotty项目，并将其更新为包含日志库。请查找项目的以下目录结构：-

[hduser@dotty dotty-example-project]$ tree
.
├── build.sbt
├── project
│   ├── build.properties
│   ├── plugins.sbt
│   └── project
└── src
    └── main
        └── scala
            └── Main.scala

5 directories, 4 files

project/build.properties：-

sbt.version=1.1.6

project/plugins.sbt

addSbtPlugin("ch.epfl.lamp" % "sbt-dotty" % "0.2.2")

build.sbt

libraryDependencies += ("com.typesafe.scala-logging" %% "scala-logging" % "3.7.2").withDottyCompat(scalaVersion.value)

libraryDependencies += ("ch.qos.logback" % "logback-classic" % "1.1.2").withDottyCompat(scalaVersion.value)

lazy val root = project
  .in(file("."))
  .settings(
    name := "dotty-example-project",
    description := "Example sbt project that compiles using Dotty",
    version := "0.1.0",

    scalaVersion := "0.9.0-RC1"
  )

src/main/scala/main.scala

import com.typesafe.scalalogging.LazyLogging

object Main extends LazyLogging{

    def main(args : Array[String]) : Unit = {
        logger.debug("Hello Dotty")
    }
}

上面的scala代码可以用

干净编译

但sbt运行失败，出现以下错误：-

正如所建议的，这可能是因为宏

---

请建议，因为我的周末项目依赖于loggin，我想将其升级为dotty。

目前，您唯一能做的就是找到另一个不需要调用宏即可使用的日志依赖项（或者检查scala日志记录的源代码，看看是否有不需要宏的替代方法来调用它）
