dotty的运行时记录器异常

Question

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https://github.com/lampepfl/dotty-example-project克隆了示例dotty项目并更新了它，包括日志库。请在下面找到项目的目录结构：-

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

5 directories, 4 files

项目/build.properties：-

sbt.version=1.1.6

项目/plugins.sbt

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

建筑sbt公司

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。斯卡拉

import com.typesafe.scalalogging.LazyLogging

object Main extends LazyLogging{

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

上面的scala代码编译良好

sbt干净编译

但sbt运行失败，出现以下错误：-

正如这里所建议的，这可能是因为宏。

请建议，因为我的周末项目依赖于loggin，我想将其升级到dotty。

目前，您唯一能做的就是找到另一个不需要调用宏就能使用它的日志依赖项（或者检查scala日志的源代码，看看是否有另一种不需要宏的调用方式）
