sbt子项目的项目目录

Question

sbt子项目是否可以有自己的project目录？或者只有根项目可以用。Scala帮助器文件为构建项目的目录？。下面是我目前的建筑结构。/my-project/sub-projects/sub-project-1/build.sbt无法访问/my-project/sub-project/sub-project/sub-project-1/subproject-1/subproject-1/subproject-1/scala中定义的对象。

/my-project
  build.sbt
  /projects
    Helper.scala
  sub-projects
    sub-project-1
      build.sbt
      /projects
        SubProjectHelper.scala

更新：sub-project-1/build.sbt中的以下sbt定义

lazy val localhost = (project in file(".")).settings (
    name := """localhost""",
    version := Common.version,
    scalaVersion := Common.scalaVersion,
    libraryDependencies ++= Common.dependencies,
    libraryDependencies ++= Localhost.dependencies
)

由于以下错误而失败

    libraryDependencies ++= Localhost.dependencies
                            ^

    at sbt.EvaluateConfigurations$.evaluateSbtFile(EvaluateConfigurations.scala:109)
    at sbt.Load$.sbt$Load$$loadSettingsFile$1(Load.scala:712)

Common在/my-project/projects/Common.scala中定义，没有问题。但是Localhost是在/my-project/sub-projects/sub-project-1/projects/sub-project-1/projects/subprojectHelper中定义的。scala在sub-project-1构建中没有正确地解析。sbt

是的，它们可以，而且您甚至不需要有子项目目录，只需将sub-project-1放在my-project目录中即可。
