Michael Osipov commented on MRESOLVER-216:
------------------------------------------
[~rodwiddowson], no issue, take your time. One of the reasons, if there is no
bug, there has been an intentional change in Resolver: All calls to properties
files are supposed to run inside a {{SynContext}}, additionally the
{{TrackingFileManager}} was synchronized. Double synchronization does not make
sense. We removed this in {{TrackingFileManager}} because we expect this to be
properly solved in {{SynContext}}. The default impl in Maven 3.8.x is no-op,
read no synchronization at all. Hence the issues. You have an additional
problem, your local repo is changed on the Jenkins agent between multiple
builds, which makes is multiprocess. For this you *must* use Redis or
Hazelcast-based synchronization [~jeboudet] has this exact setup and it runs
flawlessly for him with Redis.
