The answer is to use ConfigFactory.parseResource() in place of ConfigFactory.load().

Here is the finished result

private lazy val defaultConfig     = ConfigFactory.parseResources("conf/env/default.conf")
private lazy val environmentConfig = ConfigFactory.parseResources("conf/env/" + env + ".conf" )
private lazy val userConfig        = ConfigFactory.parseResources("application.conf")
private lazy val config = ConfigFactory.load()
                          .withFallback(userConfig)
                          .withFallback(environmentConfig)
                          .withFallback(defaultConfig)
                          .resolve()
