sbt-buildinfo生成的对象无法被引用

我正在使用前面提到的 sbt 插件来获取我正在开发的应用程序的版本。

该项目有子模块。这是主要的build.sbt

...

lazy val abandon = (project in file(".")).
  aggregate(base, cli, gui).
  dependsOn(base, cli, gui).
  enablePlugins(BuildInfoPlugin).
  settings(commonSettings: _*).
  settings(
    name := "abandon",
    fork in run := true,
    buildInfoKeys := Seq[BuildInfoKey](name, version, scalaVersion, sbtVersion),
    buildInfoPackage := "co.uproot.abandon"
  )

lazy val base = (project in file("base")).
  settings(commonSettings: _*).
  settings(
    name := "abandon-base",
    fork in run := true
  )


lazy val cli = (project in file("cli")).
  dependsOn(base).
  settings(commonSettings: _*).
  settings(
    name := "abandon-cli",
    fork in run := true
  )

lazy val gui = (project in file("gui")).
  dependsOn(base).
  settings(commonSettings: _*).
  settings(
    name := "abandon-gui",
    fork in run := true
  )

生成的BuildInfo.scala位于target/scala-2.11/src_managed/main/sbt-buildinfo/BuildInfo.scala正如预期的那样。

package co.uproot.abandon

import scala.Predef._

/** This object was generated by sbt-buildinfo. */
case object BuildInfo {
  /** The value is "abandon". */
  val name: String = "abandon"
  /** The value is "0.3.1". */
  val version: String = "0.3.1"
  /** The value is "2.11.8". */
  val scalaVersion: String = "2.11.8"
  /** The value is "0.13.12". */
  val sbtVersion: String = "0.13.12"
  override val toString: String = {
    "name: %s, version: %s, scalaVersion: %s, sbtVersion: %s" format (
      name, version, scalaVersion, sbtVersion
    )
  }
}

当我转到里面的文件时package co.uproot.abandon并尝试参考BuildInfo.version I get

Error:(256, 42) object BuildInfo is not a member of package co.uproot.abandon
    co.uproot.abandon.BuildInfo.version

我读到了子模块和这个插件的问题here https://stackoverflow.com/a/24250962/1450817并最终尝试过this https://youtrack.jetbrains.com/issue/SCL-9301#comment=27-1284275解决方法但这没有帮助。

任何帮助将不胜感激！

我想添加一张图片来说明zaxme答案，但我不能在评论中，所以我添加另一个答案以添加更多有关它的信息。

So,

1 - 右键单击target/scala-2.11/src_managed/main:

And,

2 - 选择Mark Directory as and Unmark Generated Sources Root:

然后重建，它应该可以工作。
