Ittay Dror reopened BUILDR-190:
-------------------------------
actually, sources are resolved in several places:
def from(*sources)
@sources |= sources.flatten
guess_compiler if @compiler.nil? && sources.flatten.any? { |source|
File.exist?(source) }
self
end
in the second line sources.flatten resolves the FileList
and since #from is called when 'compile' is called:
def compile(*sources, &block)
task('compile').from(sources).enhance &block
end
it is very easily resolved. in particular, after_define resolves it.
finally, since @sources is converted to Array in invoke_prerequisites, it is
hard to create prerequisite tasks that set sources using a FileList
(fwiw, i track when FileList is resolved by adding a fail in FileList#resolve
and running buildr with a non-existent task)
> make it easy to exclude java source files from compilation

> Project: Buildr
> Issue Type: Wish
> Affects Versions: 1.3.2
> Reporter: Ittay Dror
> Fix For: 1.3.4
>
>
> I have cases where there are source files that should not be compiled (and
> yet it is desired to keep them in scm).
> i can use FileList inside the project definition (assign to compile.sources),
> but then it means the files are scanned during the definition phase (where
> afterwards this project's build may not be invoked)
> it would be nice if compile.sources could be a proc (or contain proc) that is
> evaluated only before compilation
