What is a standard location for Typesafe Config file in a project directory structure?

Question

I'm a newbie to Scala and the JVM.

I've created a project via Typesafe Activator, and I'm adding configuration to it using Typesafe Config.

The documentation for Typesafe Config says that I can put the config file anywhere on the classpath under a number of different names.

Is there a standard location for each of these files?

I am also unfamiliar with determining or modifying the classpath for such a project, but that may be a separate question.

EDIT: Here is the directory structure

/home/d/projects/test/minimal-scala1/
▸ lib/
▸ project/
▾ src/
  ▾ main/
▸ scala/
  ▸ test/
▸ target/
  activator*
  activator-launch-1.2.3.jar
  activator-sbt-echo-akka-shim.sbt
  activator.bat*
  build.sbt
  LICENSE

Short Answer

If you are developing a third party lib to be used by other projects

src/main/resources/reference.conf

If you are developing a regular application

src/main/resources/application.conf

Long Answer

• system properties
  Not a file obviously. You can specify them on command line when starting the app
  sbt -Dmy.property=value run
• application.conf
  src/main/resources/application.conf
• application.json
  src/main/resources/application.json
  Note: .conf format is more commonly used, you can skip this file.
• application.properties
  src/main/resources/application.properties
  Note: .conf format is more commonly used, you can skip this file.
• reference.conf
  src/main/resources/reference.conf
  Note: Although it is meant to be provided by third party libs, but nothing prevents you from using the file in regular applications.
