Christoph Läubrich commented on MRESOLVER-372:
----------------------------------------------
[~sjaranowski] as I really like to see this fixed ( [~cstamas] *please help
here* ) as this makes maven 3.9 unusable in so many cases under windows, for a
maven plugin there is a small little chance to mitigate this by using
{code}
try (SyncContext syncContext =
syncContextFactory.newInstance(repositorySession, false)) {
Set<Artifact> lockList = new HashSet<>();
... add all interesting artifacts here ...
syncContext.acquire(lockList, null);
... do something with it ...
}
{code}
of course this is not suitable for any other third party app (e.g. IDE) outside
maven that might accessing files from the local repo.

> With the new file-locking in maven-resolver there is a problem under windows

> My suggestion would be that resolver simply uses the temp file if it can't be
> moved to final location and marks it as delete on exit. Even though this is
> not optimal, it at least ensures the the build does not fail to the cost that
> next time the file needs to be downloaded again.
