我正在使用 IvyDE Eclipse 插件来解决我的项目（我们称之为 A）的依赖关系。其中一个依赖项是我使用 sbt 构建的另一个项目（称为 B）。构建的最后一部分是调用 sbt 的 publishLocal 任务将 B 项目的工件发布到本地 Ivy 存储库。

到目前为止一切正常。但是，当我尝试解析项目 A 依赖项时，IvyDE 会生成一条错误消息，指出它无法解析“doc”和“src”jar。我可以强制它最终工作，因为它不会无法解析包含实际代码的主 jar。不过，我觉得这有点烦人。

在花了相当多的时间寻找解决方案后，

import sbt.Build
import sbt.Project
import java.io.File
import sbt.PathExtra
import sbt.SettingKey
import sbt.Artifact
import sbt.Keys.{ artifact, artifactName, artifactPath, packageSrc, packageDoc, crossTarget, projectID, scalaVersion, scalaBinaryVersion, moduleName }
import sbt.ScalaVersion
import sbt.Configurations.{ Compile }
import sbt.Configurations

/**
 * The objective here is to make the artefacts published to the local repository by the publishLocal task
 * compatible with the local resolver used by IvyDE.
 * This is achieved by dropping the classifiers from the "doc" and "source" artefacts, and by adding
 * an extra level directory to their paths to avoid clashing with the "jar" main artefact.
 */
object SbtIvyFix extends Build with PathExtra {
  lazy override val projects = Seq(root)
  lazy val root: Project = Project("xlstocsv", new File(".")) settings (
    artifact in (Compile, packageSrc) := {
      (artifact in (Compile, packageSrc)).value.copy(classifier = None)
    },
    artifact in (Compile, packageDoc) := {
      (artifact in (Compile, packageDoc)).value.copy(classifier = None)
    },
    artifactPath in (Compile, packageSrc) <<= myArtifactPathSetting(artifact in (Compile, packageSrc)),
    artifactPath in (Compile, packageDoc) <<= myArtifactPathSetting(artifact in (Compile, packageDoc)))

  // Lifted from the Sbt source artifactPathSetting() function in Defaults.scala
  def myArtifactPathSetting(art: SettingKey[Artifact]) = (crossTarget, projectID, art, scalaVersion in artifactName, scalaBinaryVersion in artifactName, artifactName) {
    (t, module, a, sv, sbv, toString) =>
      {
        t / a.`type` / toString(ScalaVersion(sv, sbv), module, a)
      }
  }
}


这工作得很好，但感觉有点过头了。有人可以提出一种更简单的方法来实现相同的结果吗？
