Hey guys,
So here is what I found. I was able to get the thread dump with Apache Maven
3.5.2 and here is the victim:

Maven stuck on obtaining file lock, in this case for:

It seems to be related to https://issues.apache.org/jira/browse/MNG-6323 and
fixed in Apache Maven 3.5.3. Indeed, I have tried Apache Maven 3.5.3 and the
issue is not there anymore, at least for me. It is reproducible 100% (just
switching from 3.5.3 back to 3.5.2 and below manifests the problem right away).
It is still not clear to me why Colm sees slow builds with 3.5.3, could be
another issue?
Regarding Jenkins, I am not able to find what is behind "Maven 3 (latest)" in
the tooling, I don't have right permissions. Dennis, John any chance you guys
could help to figure it out? Thanks.
Best Regards,
Andriy Redko

Hi Colm,
Thanks for confirming, what version of Apache Maven you are using? As a temp
workaround,
if you build with Maven 3.2.1 (or I think 3.2.x in general), the issue
shouldn't manifest.
