@AlexanderAshitkin the use case was already in
https://issues.apache.org/jira/browse/MBUILDCACHE-104 .
I paste it here:
> I have the following use case: a CI pipeline with a compile step then
multiple parallelized test steps. Tests are split in 3 groups. Each test group
execution specify the group via maven-surefire-plugin:test property 'groups'.
>
> Maven phase for compilation: process-test-classes
> Maven phase for tests: verify
>
> The compilation should use remote cache as much as possible and end up
populating it.
> Each test execution should either use the populated cache ending with
process-test-classes phase or a cache representing the result of the execution
of the current test group (value for 'groups').
>
> The issue I have is that this extension can only store a single cache
entry per input checksum. But I need to persist the build result of each test
group.
>
> The easiest solution I can think of is having 4 cache zones. The first for
the compile phase (the default zone), the 3 remaining for each test group.
>
> I need the compile phase to read/write from/to the default cache zone.
> I need each test group to read from its own cache zone then the default
cache zone, in this order. At the end, it should write to its own cache zone.
Of course, I can still open a discussion on the mailing list for such a
large change.
