Michael Osipov commented on MRESOLVER-114:
------------------------------------------
This basically means that the their {{SyncContext}} impl does not work. At
first glance, they implementation looks exactly how I expect the file locking
to look like. This means that this issue is invalid because of the former. We
need to reach out to Takari or adopt this code into ours and try to figure out
why the locking does not work as expected.

>
> 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.
