How do I fix error LGHT0094 when using SBT Native Packager?

Question

I just recently started playing around with SBT Native Packager (version 1.0.4 and 1.0.5-M3). Whenever I run:

windows:packageBin

I get the following error:

error LGHT0094 : Unresolved reference to symbol 'Directory:bin97543xxxx' in section 'Product:{98A830B8-2CC3-45EF-93DB-A5701E999432}'.

The wix file contains:

Now I don't know very much about SBT Native Packager or WiX but I'm guessing from reading DirectoryRef Element that there should be a corresponding Directory element with id bin97543xxxx that doesn't seem to be there.

I had a quick look at WixHelper.scala and WindowsPlugin.scala but it wasn't very obvious what the problem may have been. I guess it has something to do with the following from WindowsPlugin.scala:

val addBinToPath =
  // TODO - we may have issues here...
  WindowsFeature(
    id = "AddBinToPath",
    title = "Update Enviornment Variables",
    desc = "Update PATH environment variables (requires restart).",
    components = Seq(AddDirectoryToPath("bin"))
  )

Any idea how to fix this?

Answer 1

Ok so the problem here was that the bat script wasn't being created. This was because I had a multi-project build and the root project didn't have a main class.

To fix this I added the following:

mainClass in (Compile, batScriptReplacements) <<= (mainClass in (Compile, batScriptReplacements) in mainProject)

Where mainProject was the sub-project that had the main class.
