Hello all,
I would like clarifications on MNG-2802[*] that seems to be solved. If I
understand correctly it solves the problem where multiple simultaneous
Maven executions shared the same local repository.
I have been keeping for years a bit of code in my Jenkinsfiles ensuring the
local repos

to deploy a Redis server.
There apparently also is an Hazelcast-based version:

Wooohaa, thanks Thomas.
It's a whole new world being revealed to me: I wasn't aware of the huge
work happening on artifact resolvers.
At the same time, it seems not to be available out of the box (needs a
Redis server) so I'll keep my Jenkinsfile hacks for now and will wait
for proper
Yes, these are good news!

An easy fix is to run maven with one local Repo cache per executor thread.
Jenkins has a option for that. Alternatively run the whole build in a container
with Repo overlay. (I wish Jenkins had more support to prepopulate those)

It does not solve the problem. It fails miserably. Don't use it.

What’s the problem with adivisory locking, as long as Maven honors the advice
it is the same as it’s a redis lock? (But much less footprint). In fact on the
same machine it should even work without locking as Long as you use pidfiles?

Hi Bernd,
nothing is wrong with advisory file locking, as long as you don't store
local repo on NFS ;)
Will re-add file locking once I get there, as in my opinion it is the most
"lightweight" MP (multi process) solution on a single host.
Redis and Hazelcast are more for "farms", where several

Redis is so easy to install and get going in 5 minutes that I would

Even for nfs fcntl locking can work and create/ln/mv are atomic. Do you know if

are kinda Jenkins "threads").
