sbt.librarymanagement.ResolveException：使用sbt插件模块在sbt项目中下载错误

编程问答 2022-08-14

问题描述

我遇到以下问题。我有一个以以下方式描述的多模块项目。

import Build._
import sbt.Keys.scalacoptions

lazy val moduleA =
  module(id = "module-a","module-a")

lazy val moduleB =
  module(id = "module-b","module-b")

lazy val root =
  module(id = "sample-project",directory = ".")
    .aggregate(moduleA,moduleB)

lazy val plugin = Project(id = "plugin",base = file("plugin"))
  .settings(
    sbtPlugin := true,name := "MyPlugin"
  )
  .dependsOn(moduleA)

Build声明以下帮助者的地方

object Build {
  val scala212 = "2.12.11"
  val scala213 = "2.13.3"
  val projectScalaVersion = scala213
  val supportedScalaVersions = List(scala213,scala212)

  val projectVersion = "0.3.5-SNAPSHOT"
  val projectOrganization = "com.example"

  val commonSettings = Seq(
    version := projectVersion,crossScalaVersions := supportedScalaVersions,organization := projectOrganization,scalaVersion := projectScalaVersion,scalacoptions += "-deprecation",scalafmtOnCompile := true
  )

  def module(id: String,directory: String): Project = {
    Project(id = id,base = file(directory))
      .settings(commonSettings: _*)
  }

  implicit class ProjectOps(project: Project) {
    def libraries(modules: ModuleID*): Project = {
      project.settings(libraryDependencies ++= modules)
    }

    def disablePublish: Project = {
      project.settings(publishLocal := {},publishM2 := {},publish := {})
    }
  }
}

我正试图添加一个sbt插件以使用任务公开项目的某些部分。 不幸的是，在编译插件时，出现以下错误：

sbt:sample-project> plugin/compile

我不知道为什么会这样。任何帮助或技巧，以解决此问题将不胜感激。
