docker:stage problem - no application is built

[johnthuss]

I'm testing out the new docker:stage task and having a problem. The first time I ran it, it generated the Dockerfile and a directory structure like "files/opt/docker/..." but without anything other than directories. Since then when I run it only the Dockerfile is created. If I clean first, and then do docker:stage it's not even running a compile or anything to create the application. The Dockerfile is the only thing being created.

sbt.version = 0.13.5
sbt-native-packager = 0.7.4
scala = 2.10.4
Mac OS X 10.8.5
Play 2.2.2

Okay. The stage task should generate all files, but no image.
Can you share your build.sbt or a subset to reproduce?

$ cat build.sbt

name := "my app"

libraryDependencies ++= Seq(
  "commons-collections"       % "commons-collections"  % "3.1",

Thanks. I'll take a closer look on monday. In the meantime @fiadliel may know
some more Details.

There seems to be an issue with your build configuration, because Play already includes packaging settings.

You should not include packagerSettings, deploymentSettings or archetype.java_server - that may be overriding/removing important settings.

See also playframework/playframework#2915

I'm AFK for the week, so I can't easily find out exactly why this breaks the build right now.

[johnthuss]

Thank you. Removing those parts fixed it.
