Re: [sbt] package task with arguments to create a file

[Havoc Pennington]

Hi,

Without working this out entirely myself, I can give you some pointers
in the right direction maybe. Assuming 0.12.x

First be sure to know the basics from Getting Started
http://www.scala-sbt.org/release/docs/index.html from Welcome down
through Custom Settings and Tasks.

Second I think you will need a custom task, like your my-package, and
to take parameters it needs to be an InputTask. with a parser for the
parameters. See
http://www.scala-sbt.org/release/docs/Extending/Input-Tasks.html

Third to implement your custom task, I'm not sure of the very best
approach. The problem is that if you depend on the existing "package"
then it would run before your task, so you couldn't modify its
settings such as the file it outputs. However... the simplest hack
might be to depend on "package" (which will give you the File it
creates) and then just copy or rename the jar you get based on your
InputTask parameters. The Getting Started stuff is hopefully clear on
how to do this dependency.

Hope that gets you started... maybe someone else will have a better approach.

Just a note, you can depend on "mappings in (packageBin,Compile)", and this will give you a Seq[(File, String)]  (or a sequence of files and filenames ot place in a zip), which you could filter/expand based on your input.

Hi,

Thanks for both answers. I'll have a look at the links you provided. However that's not just the name of the jar file I want to rename. I need to create a ressource file in the jar.

Then I'll have a look on the suggestion of the dependency on the mappings, even if I'm not sure yet to understand what it really means. 

I'll put some info as soon as I get something working or almost working.

Hi,

I finally managed to create the Input Task.

But I don't really get how to depend on "mappings in (packageBin,Compile)". For the moment, my Input Task is defined with an InputKey[Unit]. Should it be something else ?

How do I write the dependency ?

Thanks !!
Matt
