OSX Play Framework Auto-Reload

I've been cleaning the internet for hours, there are many "useful" tips ... which cause nothing but problems.

This is me, almost exactly:

Load the auto-loading framework into a docker container

I'm using the latest (I don't know how to check, but I downloaded it a week ago) version of the game! Framework inside a ubuntu docker container with Java 8, built with the following dockerfile:

FROM ubuntu:latest
MAINTAINER [REDACTED]
RUN sudo apt-get update
RUN sudo apt-get -y install software-properties-common
RUN sudo apt-add-repository ppa:webupd8team/java
RUN sudo apt-get update
RUN echo oracle-java8-installer shared/accepted-oracle-license-v1-1 select true | sudo /usr/bin/debconf-set-selections
RUN sudo apt-get -y install oracle-java8-installer
RUN java -version

      

        
        
        
      

    

Several sources on the Internet show the same or similar problems, and more or less come to the same conclusion . I run my game app like this:

I will not repeat what was linked above, it is basically an identical situation. (File changes were detected, it shows compilation, although the webpage does not reflect the changes.) Also, I check the correct compiler by decompiling the generated .class files, displaying the correct code.

Now when I say the magic words: by adding the following line to build.sbt file

PlayKeys.playWatchService := play.sbtplugin.run.PlayWatchService.sbt(pollInterval.value)

      

        
        
        
      

    

I am getting a generic build.sbt file:

name := """cms-work"""

version := "1.0-SNAPSHOT"

retrieveManaged := true

lazy val root = (project in file(".")).enablePlugins(PlayJava)

scalaVersion := "2.11.6"

libraryDependencies ++= Seq(
  javaJdbc,
  cache,
  javaWs
)

// Play provides two styles of routers, one expects its actions to be injected, the
// other, legacy style, accesses its actions statically.
routesGenerator := InjectedRoutesGenerator

// Polling for auto-reload, because networked filesystem.
PlayKeys.playWatchService := play.sbtplugin.run.PlayWatchService.sbt(pollInterval.value)

      

        
        
        
      

    

Running ./activator

in my project directory forces it to reevaluate my build file and create the following:

/root/cms-work/build.sbt:23: error: value playWatchService is not a member of object play.sbt.Play.autoImport.PlayKeys
PlayKeys.playWatchService := play.sbtplugin.run.PlayWatchService.sbt(pollInterval.value)
         ^
[error] Type error in expression

      

        
        
        
      

    

As you can see, a solution of one size fits all is no longer applicable. Since then, I've been at a dead end. I found absolutely no notice of any changes from 2.3.x that would invalidate this command. Instead, I see things that mention "works after 2.3.2" that I am.

PS:

Can anyone explain the odd Ctrl-D behavior described at the end of the linked post. I am experiencing the same thing, it seems very strange considering the fact that Ctrl-D should exit ...
