[2.2-Scala] Add a custom start script to the dist package

[Ryan Tanner]

If I'm using the "dist" task to create a standalone distributable, how can I add a custom start script to the bin/ folder?  I have a number of options like SSL settings that I would like to include in that but I can't figure out how to modify the SBT Native Packager to do this.  I tried appending a (File, String) tuple to mappings in Universal as the packager docs say but I can't figure out how to even make that compile.

Any ideas?

I've used the following in my build.sbt to include static files:

mappings in Universal <++= (packageBin in Compile) map { jar =>
  val scriptsDir = new java.io.File("res/scripts/")
  scriptsDir.listFiles.toSeq.map { f =>
    f -> ("bin/" + f.getName)
  }
}

Thanks, that worked.

If you create a dist folder in your project then it will be used as a template. Thus if you have a dist/bin with a script in it, the script will appear in your final distribution.

I've created an issue to improve our docs in order to explain this:

Good tip Cranston. A quick question to the list, what does the following line mean in English?

mappings in Universal <++= (packageBin in Compile)

I'm guessing these are scopes, or build phases.

But what are 'mappings in Universal' ?

And what does this weird symbol '<++=' mean?

Thanks,

Bryan

As mentioned the supported way is to use a dist folder as a template in your project.

The 'Universal' and 'Compile' are scopes.

<++= means to append a task.
