I also tried:
* replicate local repo to dedicate for sonar:sonar maven instance
* latest 3.9.0 from source
Same locking found
> multiple maven instances working same source tree can lock each other

> Key: MNG-7433
> URL: https://issues.apache.org/jira/browse/MNG-7433
> Project: Maven
> Issue Type: Bug
> Affects Versions: 3.8.5
> Reporter: Dan Tran
> Priority: Major
>
> I have a large multi modules java maven build where:
> * phase 1 - basic build + unit tests + jacoco - 40 min
> * phase 2 - sonar:sonar 20 min
> * phase 3 - final packaging and basic smoke-test - 20 min
> To take advantage of Maven multi-threaded build, during the reactor build,
> one of our maven module spins another instance of Maven to run sonar:sonar
> goal right after the basic build is done.
> This means our phase 2 and phase 3 run in parallel sharing the same source
> tree, same local maven repo (where sonar:sonar should have all needed
> dependencies at the share local maven repo to run its task)
> With maven-3.8.5, parallelization is no longer possible, phase 3 is blocked
> until phase 2 is done.
> I am able to trace it to https://github.com/apache/maven/pull/628 where the
> locking started the happen
> How does the lock mechanic work? there must be a local file where both Maven
> instances are watching each other. Is there an option to disable this lock?
