Xavier Hanin commented on IVY-1011:
-----------------------------------
One issue with parallel downloading is download progress reporting. When used
from Ant, we are very limited in reporting, output to console being done only
by whole lines. I guess this is not a showstopper if we don't get something
clean during parallel downloads, but we need to be careful with this IMO.

> Key: IVY-1011
> URL: https://issues.apache.org/jira/browse/IVY-1011
> Project: Ivy
> Issue Type: New Feature
> Components: Core
> Reporter: Jan Matèrne
> Priority: Minor
>
> Enhance the downloading of artefacts.
> - parallel downloads
> - resuming a download
> - partial downloads
> - using a downloadmanager (for getting the first three topics)
> (Without knowing the internals) I think of something like
> public interface Downloader {
> /**
> * @param source From where to download
> * @param target where to store the artefact
> * @param progressReporter something that reports the progress (the
> [.......]ok at the moment)
> */
> download(URI source, File target, ?? progressReporter);
> }
> Implementations:
> - SerialDownloader : the existing downloader
> - ParallelDownloader : starts multiple downloads in parallel
> - SunDownloader : uses Suns Downloadmanager [1] for doing the job
> - ??Downloader : other (free available Java based) download manager
