title: Parallel downloads of Maven artifacts
body: <p>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 with downloading the dependency JARs with up to 5 threads in parallel.</p>
  
  <p>What's the reason for not using parallel downloads for the POMs also?</p>
  
  <p>Is there an option to configure the number of parallel downloads of either POMs or JARs?</p>
