How to exclude .scala source file in project folder?
Hendy Irawan
I'm using sbt 0.11.0.
I'd like to exclude a .scala file because when I run "sbt console" it
complains:
> compile
[info] Compiling 1 Scala source to /home/ceefour/git/bippoadmin/butler/
target/scala-2.9.1/classes...
[error] /home/ceefour/git/bippoadmin/butler/butler.scala:1: expected
class or object definition
[error] val butler = id.co.bippo.devops.Butler.load
[error] ^

compile:compile: Compilation failed
[error] Total time: 0 s, completed 12 Okt 11 10:50:04
The strange thing is butler.scala is not even in the source
directories (which are src/main/scala), but still compiled by sbt? Is
this a bug?
How to do this? Thank you.

The project base directory is by default a source directory in addition to src/main/scala. You can exclude source files by name like:
excludeFilter in unmanagedSources := "butler.scala"

excludeFilter is normally defined (if I'm reading Defaults.scala
correctly) as:
> excludeFilter :== (".*" - ".") || HiddenFileFilter
Does setting it to be "butler.scala" not result in hidden files no
longer being excluded? And what (if any) are the bad effects of this?
Not a big thing, but I just want to make sure that I'm understanding
things correctly :-)
Thanks!

a related question to filtering - i want to filter out test resources (the resources are located in the source directory), however the following does not work:
Seq(...
resourceDirectory in Test <<= (javaSource in Test) (js => js),
excludeFilter in resources in Test := "*.java"
)

Keep in mind scopes: https://github.com/harrah/xsbt/wiki/Getting-Started-Scopes
It's a little hard to unpack this from the sbt command line because
the filters' values just show up as "sbt.SimpleFileFilter@8bfdea" when
you "inspect exclude-filter"
But if you look where the excludeFilter :== definition you mention is
defined in Defaults.scala, it's "inScope(GlobalScope)" so that is
defining */*:exclude-filter
Mark's suggestion is to define
excludeFilter in unmanagedSources := "butler.scala"
which is specifically for the unmanagedSources task only rather than global.
That already has a whitelist:
includeFilter in unmanagedSources :== "*.java" | "*.scala"
I think you may be right that hidden files would no longer be
excluded, but unless your hidden files end in .scala or .java then
perhaps it won't really matter since they won't be in the
includeFilter.
If you messed with excludeFilter globally rather than in
unmanaged-sources, there could maybe be more side effects, I don't
know.

Yes, you're right, perhaps I simplified the answer too much.

The main reason you'd probably want to keep the hidden file exclusion is to exclude source files in .svn directories, for example. You can augment the current filter instead of completely replacing it with something like:
excludeFilter in unmanagedSources ~= { _ || "butler.scala" }
which is equivalent to:
excludeFilter in unmanagedSources <<=
(excludeFilter in unmanagedSources) { (currentFilter: FileFilter) =>
currentFilter || "butler.scala"
}

That should be unmanagedResources instead of resources (for sources, it is unmanagedSources). The reason is that sbt only automatically traverses unmanaged resource directories looking for resources. 'resources' contains both 'unmanagedResources' and 'managedResources' and no filtering is done on 'resources'.
