sbt to exclude source directory

[TH Lim]

Hi,

I like to obsolete my Java sources and leave them in its default
directory, src/main/java and exclude them from compilation. How do I
config build.sbt to exclude src/main/java directory? Also, can I
exclude a file or group of files specify with RE. Can these be easily
configured in build.sbt?

Thanks

Hi,

Well, there might be a better way but I'd add this to my build.sbt:

javaSource in Compile := file("some/path/that/doesnt/exist")

For direct control over the source directories used, you can directly define the unmanagedSourceDirectories task, which produces a valud of type Seq[File].

For example, if you only want the src/main/scala directory:

unmanagedSourceDirectories in Compile <<= baseDirectory(base =>
(base / "src" / "main" / "scala") :: Nil
)

There is basic support for glob filters. See Paths[1]. Also, there is PatternFilter[2], which accepts a java.util.regex.Pattern. The settings to configure are sourceFilter to define the sources that should be included and/or defaultExcludes to exclude sources:

sourceFilter in unmanagedSources := "*.java" | "*.scala"

defaultExcludes in unmanagedSources := "*Test.java"

(In 0.11.0, these names are deprecated in favor of includeFilter and excludeFilter for consistency with resource and classpath filters.)
