Weird directory structure

[binarykitchen]

I have for example tried this in a new fork

(deftask package []
  (comp
    (download :url     (format "https://unpkg.com/@microsoft/office-js@%s/dist/office.debug.js" +lib-version+)
              :target  "cljsjs/office-js/development/office-js.inc.js")
    (download :url     (format "https://unpkg.com/@microsoft/office-js@%s/dist/office.js" +lib-version+)
              :target  "cljsjs/office-js/production/office-js.min.inc.js")
    (sift :include #{#"^cljsjs"})
    (pom)
    (show :fileset true)
    (jar)
    (validate-checksums)))

but output is very wrong

Trying to understand what causes this wrong directory structure? Why is there so much nesting?

Thanks for any clues

When I am trying to use :name instead I think there is a bug in the download task at (re-pattern fname) which probably should be quoted or so. And it it's a regex, it looks weird when printed in console
