Build.scala:1: not found: object sbt - scala

Question

I am using sbt version 1.0
$ 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
I am using IntelliJ IDEA v14.1.3 for my project and the structure looks like
As you may see that project was not able to resolve Build. When I try command-line to run sbt, I see
$ sbt

I am very new to Scala, sbt so no idea what is going wrong with it

Answer 1

The MyBuild.scala was at root. It should be inside project folder. I made that change and now it works. Thanks to tpolecat on IRC who helped me with this

Answer 2

I have a multi-project sbt build, and two of the projects were declaring two of the same val in their build.sbt files. I moved the duplicated val (s) to the Build.scala in the root project as def, and error stopped. Found the answer here: https://github.com/sbt/sbt/issues/1465
example: val samza_gid = "org.apache.samza" in build.sbt file became
def samza_gid = "org.apache.samza" in the Build.scala file.
