Multi-project build not working

[nicl]

Hi, I'm trying to package a multi-project build into a single zip file.

lazy val commonSettings =
  net.virtualvoid.sbt.graph.Plugin.graphSettings ++
    scalariformKeysPref ++
    scalariformSettings

lazy val api = (project in file("api"))
  .settings(commonSettings)

lazy val integration = (project in file("integration"))
  .settings(commonSettings)
  .dependsOn(api)

lazy val root = (project in file("."))
  .enablePlugins(UniversalPlugin)
  .settings(
    name := "api",
    version := "1.0"
  )
  .aggregate(api, integration)
  .dependsOn(api, integration)

When I run packageZipTarball I'm get errors like:

(root/universal:packageZipTarball) java.io.IOException: Cannot run program "tar" (in directory "/var/folders/wp/xl36r_2s4595xndg3k75hbz80000gp/T/sbt_8cc085f6/api"): error=2, No such file or directory

Can someone point me to docs/help on how to get this working? At the moment it looks like it is not finding any files to bundle into the zip. I could manually specify the mappings, but I feel like there must be an easier/more correct solution here.

Thanks.

UPDATE: figured out a solution:

mappings in Universal <++= (sourceDirectories in (api, Compile)).map(dirs => dirs.flatMap(d => directory(d))),

in settings for the root project. Would be good to know if this is the 'recommended' way but it seems to work fine.

Update: in fact the advice above is not great. For posterity, the thing I was doing wrong was I'd actually managed to delete the 'dependsOn' for the root project somehow.

Thanks for sharing. I hadn't had time to take a look so far.

I think the issue here is that you need to understand sbt multi-project builds well enough before trying to use sbt-native-packager with one. Which is fair enough I guess but does require a closer reading of the sbt docs http://www.scala-sbt.org/0.13/docs/Multi-Project.html.

Yes 😄
