I just wanted to mention here that I came across sbt-compile-quick-plugin (https://github.com/etsy/sbt-compile-quick-plugin).

You could add the following line to build.sbt:

sources in Compile <<= (sources in Compile).map(_ filter(_.name == "Particular.scala"))

Then fix Particular.scala, then edit build.sbt and put the name of the next source file. If you keep the sbt console open, reload will re-read the .sbt file after you modify it.
