------------------------------------
Summary: 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
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.
