> Filter#run updates target timestamp when there are directory mappings

> Key: BUILDR-249
> URL: https://issues.apache.org/jira/browse/BUILDR-249
> Project: Buildr
> Issue Type: Bug
> Components: Core features
> Affects Versions: 1.3.4
> Reporter: Ittay Dror
> Fix For: 1.5
>
>
> Filter#run first creates a variable, copy_map for all destinations that need
> refreshing (older than source)
> Then if the copy_map is not empty, it iterates each entry, if the source is a
> directory, it creates the destination directory and continues. At the end it
> touches the root target directory.
> Since if the destination directory exists, it is not touched (mkpath doesn't
> change timestamps), the result is that if there is a source directory newer
> than an existing destination directory, they will always appear in copy_map
> and as a result the root target timestamp is always updated, which causes the
> jar task to alwyas run, which cases all those dependent on it to recompile.
> I guess this is not evident normally, because of bug BUILDR-205 which causes
> the filter task to not run at all if the root target already exist, but since
> I wanted resources to actually be copied when needed, I worked around the bug
> by forcing the task to always run.
