Palash Das commented on MRESOLVER-7:
------------------------------------
You people keep fighting over decency of a PR or deadlocks of multi threaded
downloads, but in reality this forces us to pay free money to the cloud
providers for CI time.
When we have
# sufficient network bandwidth
#
High speed SSD
# And good amount of cpu
*we still have to pay 3 hrs of CI time just to download 3.4GBs of jar files.*
Great collaboration skills guys. Great appreciations towards the OSS efforts
that people show on their PRs. Approve the PR, merge it and revert it within 1
month. Awesome reward received.
Time will come when we will switch the build tool instead of a dependency
plugin. Cheers to gradle / bazel. Those comment fights will be remembered!

> Key: MRESOLVER-7
> URL: https://issues.apache.org/jira/browse/MRESOLVER-7
> Project: Maven Resolver
> Issue Type: Improvement
> Affects Versions: Aether 1.0.2
> Reporter: Harald Wellmann
> Priority: Major
> Time Spent: 40m
> Remaining Estimate: 0h
>
> h3. Background
> When building a project with dependencies not yet available in the local
> repository, I noticed that Maven 3.3.9/Aether 1.0.2 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.
