> Download dependency POMs in parallel
> Key: MNG-5896
> URL: https://issues.apache.org/jira/browse/MNG-5896 > Project: Maven
> Issue Type: Improvement
> Components: Dependencies
> Affects Versions: 3.3.3
> Reporter: Harald Wellmann
> Priority: Major
> Fix For: 3.6.x-candidate, needing-scrub-3.4.0-fallout
> h3. Background
> When building a project with dependencies not yet available in the local repository, I noticed that Maven 3.3.3 first downloads the dependency POMs _sequentially_ and then proceeds downloading the dependency JARs with up to 5 threads _in parallel_.
> Due to this, when first building a project with a large number of dependencies, downloading a large number of small POMs may take a lot longer than downloading the much larger JARs, or even longer than building the project itself, especially when a repository manager is used which increases the download latency.
> h3. Enhancement
> Download POMs of (transitive) dependencies in parallel to significantly speed up initial builds of large projects.
