I wrote this scala code

package com.abhi

import java.io.File

object Main1 {
    def main(args: Array[String]) : Unit = {
        println("Main1 Hello World")
    }
}

object Main2 {
    def main(args: Array[String]) : Unit = {
        println("Main2 Hello World")
    }
}

and this built.sbt file

name := "Foo"

version := "1.0"

scalaVersion := "2.11.6"

libraryDependencies ++= Seq(
    "org.scalatest" % "scalatest_2.11" % "2.2.4" % "test"   
)

mainClass:= Some("com.abhi.Main1")

But when I run sbt run it still says 

[warn] Multiple main classes detected.  Run 'show discoveredMainClasses' to see the list

Multiple main classes detected, select one to run:

 [1] com.abhi.Main1
 [2] com.abhi.Main2

Enter number:

Why is it still asking me for which class to chose? The main class to choose was already specified in the build.sb

See the answer to How to set main class in build?

You'll need something like:

mainClass in (Compile, run) := Some("com.abhi.Main1")
