Build.scala:1: 未找到：对象 sbt

Question

我正在使用 sbt 1.0 版

$ sbt version
[info] Loading project definition from /Users/harit/code/learningScala/project
[info] Set current project to learningScala (in build file:/Users/harit/code/learningScala/)
[info] 1.0

我正在为我的项目使用 IntelliJ IDEA v14.1.3，结构看起来像

如您所见，该项目无法解析 Build。当我尝试使用命令行运行 sbt 时，我看到

$ sbt 
[info] Loading project definition from /Users/harit/code/learningScala/project

我对 Scala、sbt 很陌生，所以不知道它出了什么问题

Answer 1

MyBuild.scala 在 root。它应该在 project 文件夹中。我做了那个改变，现在它起作用了。感谢 IRC 上的 tpolecat 帮助我

Answer 2

我有一个多项目 sbt 构建，其中两个项目在它们的 build.sbt 文件中声明了两个相同的 val。我将重复的 val (s) 作为 def 移动到根项目中的 Build.scala，错误停止了。在这里找到答案：https://github.com/sbt/sbt/issues/1465

示例：val samza_gid = "org.apache.samza" 在 build.sbt 文件中变为 def samza_gid = "org.apache.samza" 在 Build.scala 文件中。
