------------------------------------------
Let me try to find someone with enough experience whoe wants to help on this
topic.
> ArtifactNotFoundExceptions when building in parallel
> ----------------------------------------------------
>
> Key: MRESOLVER-114
> URL: https://issues.apache.org/jira/browse/MRESOLVER-114
> Project: Maven Resolver
> Issue Type: Bug
> Components: resolver
> Affects Versions: 1.4.2
> Reporter: Rainer Reich
> Priority: Major
> Attachments: maven-debug-log.txt
>
> Time Spent: 20m
> Remaining Estimate: 0h
>
> We have a multi-module project with quite many modules and many dependencies
> and observe pretty random {{ArtifactNotFoundExceptions}} when building in
> parallel with an empty local repository.
> The "funny" thing is that Maven did in fact download the jar that it
> complained about not finding.
> In this example Maven said it could not find
> {{edu.tum.cs:cup-runtime:jar:11a}} (see stacktrace below)
> But it also said: {{Downloaded from central-mirror:
> [https://mirror.xy.com/repository/maven-all-mirror/edu/tum/cs/cup-runtime/11a/cup-runtime-11a.jar]}}.
> When looking into the local repository after the failed build we found the
> cup-runtime.jar in the correct place with the correct checksum.
> We tried the following to "fix" the problem:
> * build with and without the takari extensions ({{takari-local-repository}}
> & {{takari-smart-builder}}) using {{--builder smart}}
> * also build with {{io.takari.aether:aether-connector-okhttp}} extension
> * only execute goal package instead of install
> * build with these properties: {{-Daether.connector.basic.threads=1
> -Daether.connector.resumeDownloads=false}}
> But nothing helped.
> Unfortunately it seems to be a race condition and we cannot reproduce it
> consistently but it happens in about 1 out of 5 builds.
