Adrian Tarau commented on MNG-7539:
-----------------------------------
I am unable to replicate the issue outside of the closed-source project, and
cannot determine why it is behaving abnormally. The POM appears to have the
correct settings in the appropriate places.
> Validate/Download SNAPSHOT dependencies once
> --------------------------------------------
>
> Key: MNG-7539
> URL: https://issues.apache.org/jira/browse/MNG-7539
> Project: Maven
> Issue Type: Improvement
> Components: Dependencies
> Reporter: Adrian Tarau
> Assignee: Tamas Cservenak
> Priority: Major
>
> Building an unreleased multi-module project (30-40 modules) that depends on
> various other unreleased modules puts significant pressure on the Maven
> Repository (a local Nexus instance), and artifact resolution could slow down
> the build 2x-3x.
> I do acknowledge that it is the job of the repository to cache and serve
> those responses fast, and for some reason, sometimes it slows down without an
> apparent reason.
> However, the whole build process will be faster if Maven validates a SNAPSHOT
> once for multi-module (when the dependency is reached the first time) and
> then use that version. Even if Maven Repository is relative fast, there is
> still network traffic done. Outside the fact that it should not be done, it
> might also introduce flaky behaviors:
> * one module downloads a version of artifact A, works with it, and
> everything is fine
> * 10 minutes later, another module needs artifact A and gets a newer
> version, which has some issues, and various (test) failures will be raised
> For consistency, on a multi-module build, all modules should _see_ the same
> version of a SNAPSHOT artifact. It will be faster, and it will be consistent
> (which is very important).
