Packaging Play application for windows using Native sbt Packager

Question

I have made a small HTTP serveur with play. I want now to buil a windows version with an install. I have already made one few month ago but I have modified my application so I have to remake an install. But, without changing everything in the sbt file, it fail...

Here the command I use for building the install :

activator windows:packageBin

Here the error I get when I launch the application after installation :

Oops, cannot start the server.

And here my sbt file :

name := """IDTabDriver"""

name in Windows := "IdTabDriver"

packageSummary in Windows := "IdTabDriver"

packageDescription in Windows := "IdTabDriver"

maintainer in Windows := "My Company"

organization := "My Company"

version := "1.0.0.1"

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

scalaVersion := "2.11.1"

libraryDependencies ++= Seq(
  cache,
  javaWs,
  "commons-configuration" % "commons-configuration" % "1.10",
  "org.rxtx" % "rxtxcomm" % "2.0-7pre1"
)

If any one have an idea, I have tried so much things I can't find solution

Answer 1

I also encountered the same error complaining that the resource application.conf is not found on classpath. This might be related to a know bug in sbt-play plugin. Until the recent bug fix is released, try adding the following line to your build.sbt as a workaround as suggested by the Play development team.

PlayKeys.externalizeResources := false

This worked for me.
