scala - sbt.ResolveException：未解决的依赖项：org.scalamacros#scalac-plugin_2.12.3;2.0.0-96-9f738df2
问题描述
想看看是否有主题行错误的解决方案。直到几天前，没有任何改变的 build.sbt 原样起作用。这是专注于构建设置的片段（该项目有一个宏和一个核心）：
lazy val ScalamacrosVersion = "2.0.0-96-9f738df2"
lazy val macroSettings: Seq[Def.Setting[_]] = Seq(
name := "gBoxCPCommonsMacros",
organization := "me.ganaakruti",
version := "1.0",
addCompilerPlugin("org.scalamacros" %% "paradise" % "2.1.0" cross CrossVersion.full),
addCompilerPlugin("org.scalamacros" % "scalac-plugin" % ScalamacrosVersion cross CrossVersion.full),
scalacOptions += "-Xplugin-require:macroparadise",
scalacOptions in (Compile, console) := Seq(),
sources in (Compile, doc) := Nil,
//macro paradise plug-in doesn't work in REPL yet.
scalacOptions in (Compile, console) ~= (_ filterNot (_ contains "paradise")),
libraryDependencies ++= Seq(
"org.scala-lang" % "scala-reflect" % "2.12.3",
"ch.qos.logback" % "logback-classic" % "1.1.3"
)
)
这是异常跟踪（尝试存储库更改，但没有结果）。似乎到 scalac repo 的链接已失败。该链接给我一个404。有什么想法吗？：

解决方案
一种解决方法是手动将插件 jar 放在源的 baseDirectory 中的 custom_lib 下，并分配给 build.sbt 中的 scalacOptions。这是摘录：
//Unmanaged base - brings custom libraries into the app path scope
unmanagedBase := baseDirectory.value / "custom_lib"
....
lazy val macroSettings: Seq[Def.Setting[_]] = Seq(
name := "gBoxCPCommonsMacros",
organization := "me.ganaakruti",
version := "1.0",
addCompilerPlugin("org.scalamacros" %% "paradise" % "2.1.0" cross CrossVersion.full),
scalacOptions += "-Xplugin-require:macroparadise",
scalacOptions += s"-Xplugin:$unmanagedBase/scalac-plugin_2.12.3-2.0.0-96-9f738df2.jar",
scalacOptions in (Compile, console) := Seq(),
sources in (Compile, doc) := Nil,
//macro paradise plug-in doesn't work in REPL yet.
scalacOptions in (Compile, console) ~= (_ filterNot (_ contains "paradise")),
libraryDependencies ++= Seq(
"org.scala-lang" % "scala-reflect" % "2.12.3",
"ch.qos.logback" % "logback-classic" % "1.1.3"
)
)
但是，在某些时候想回到使用存储库链接来做这件事，因为它以前可以工作。不确定是否需要重新访问 lib 依赖项。希望借鉴别人的经验。现在，过去的构建问题。
