Réda Housni Alaoui updated MBUILDCACHE-104:
-------------------------------------------
Summary: Allow multiple cache entries for a single checksum (was: Allow to
distinguish 2 kinds of remote cache url: one for read and one for write)
> Allow multiple cache entries for a single checksum
> --------------------------------------------------
>
> Key: MBUILDCACHE-104
> URL: https://issues.apache.org/jira/browse/MBUILDCACHE-104
> Project: Maven Build Cache Extension
> Issue Type: New Feature
> Reporter: Réda Housni Alaoui
> Priority: Major
>
> 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 remote cache zones. The first
> for the compile phase, the 3 remaining for each test group.
> I need the compile phase to read from the first remote cache zone and *write
> to all remote cache zones*. I need each test group to read/write from/to
> their respective cache zones.
> I propose to split the remote cache configuration between readable cache and
> writable cache and to allow multiple remote writable cache locations.
