           Summary: dub: running single-file package as pre generate
                    command always rebuilds
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: P1
         Component: tools

          Reporter: doob@me.com

If a single-file Dub package is used as a pre generate command the project containing the pre generate command will always be rebuilt. This happens because the path to the single-file package is not correctly added to the package. This will later lead to the current directory, `.`, being added as a dependency instead of the path to single-file package. This happens to the DMD Dub package.
