Description

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.
