scala - 使用scala宏时，为什么编译错误stacktrace看起来如此不连贯？

Question

我想在一些不可靠的宏上试验scala。因此，我模仿了无形调用中的一个简单错误:

import shapeless.Witness

    val v = Witness(Random.nextInt())

然后我用 gradle build --info --stacktrace编译它，期望找到一个以'shapeless.Witness'或类似的东西开头的异常。相反，我得到了这个:

> Task :common:compileTestScala
[Error] /home/peng/git-spike/scalaspike/common/src/test/scala/com/tribbloids/spike/shapeless_spike/RefinedType/Creation.scala:12: Expression scala.util.Random.nextInt() does not evaluate to a constant or a stable reference value
one error found

> Task :common:compileTestScala FAILED

这对我有什么帮助？我只能看到 shapeless.Witness的代码，看不到整个 sbt.internal.inc.AnalyzingCompiler。我应该怎么做才能看到与实际报告该错误的宏有关的错误？
更新1 我也代表Dmytro Mitin附加我的构建配置:

allprojects {

    apply(plugin = "java")
    apply(plugin = "java-library")
    apply(plugin = "scala")

...

    dependencies {

        implementation("org.scala-lang:scala-compiler:${vs.scalaV}")
        implementation("org.scala-lang:scala-library:${vs.scalaV}")
        implementation("org.scala-lang:scala-reflect:${vs.scalaV}")
<vs.scalaV=2.12.11>
... 
<witness is introduced in s submodule>
    }

    tasks {

        val jvmTarget = JavaVersion.VERSION_1_8.toString()

        withType<ScalaCompile> {

            targetCompatibility = jvmTarget

            scalaCompileOptions.loggingLevel = "debug"

            scalaCompileOptions.additionalParameters = listOf(
                    "-encoding", "utf8",
                    "-unchecked",

                    "-Yissue-debug"
            )
        }
    }
}

更新3 我终于在sbt上尝试过，但是显然不能启用宏stacktrace选项。这是sbt构建文件中的scalac配置:

scalacOptions ++= Seq(
  "-unchecked",
  "-deprecation",
  "-feature",
  //                            "-Xfatal-warnings",
  "-Xlint:poly-implicit-overload",
  "-Xlint:option-implicit",
//  "-Xlog-implicits",
//  "-Xlog-implicit-conversions",
  "-Yissue-debug"
)
scalacOptions in (Compile, doc) ++= Seq("-groups")

/** Enable for debugging */
testOptions in Test += Tests.Argument("-oF")

然后，它显示的信息甚至少于maven和gradle:

我在这些构建系统中是否缺少任何东西？

Answer 1

是否有其他编译器错误为您提供有用的堆栈跟踪信息？
从根本上讲，堆栈跟踪是运行时的事情:在编译时唯一可以拥有的堆栈跟踪是编译器内的堆栈跟踪(例如问题堆栈跟踪中的sbt.compiler包)。
通常，要调试宏问题，具体取决于问题，您可以:

如果所讨论的宏无法扩展

，请在调试器(存在 instructions)中运行Scala编译器

使用-Ymacro-debug-lite编译器选项转储生成的代码，这将为您提供生成的Scala代码和抽象语法树表示形式；这仅在宏扩展但自身无法编译或出现运行时错误

的情况下才有用
