>                 Key: MNG-6958
>                 URL: https://issues.apache.org/jira/browse/MNG-6958
>             Project: Maven
>          Issue Type: Improvement
>          Components: maven wrapper
>    Affects Versions: 3.6.3
>         Environment: linux.
>            Reporter: Brett Sutton
>            Priority: Major
>   Original Estimate: 24h
>  Remaining Estimate: 24h
>
> I have a large project which we use docker for deployments.
>  
> Doing a docker build using maven takes a very long time as maven must download all of the artefacts each time (yes there are work around for this but during early dev these usually fail).
> The main performance issues appears to be that maven only downloads the .pom files using a single thread.
> Jars appear to honour the -T option but pom's just ignore it.
>  
> The result is that a build that should only take a few minutes takes closer to half an hour.
> This is really a major performance bottle neck for maven.
