[Feature]: Spock integration should not export Spock dependency #7540

Open musketyr opened 9 months ago

musketyr commented 9 months ago

Module

None

Problem

Spock is always released against the multiple Major versions of Groovy. For example version 2.3 has been released for Groovy 2.5, 3,0 and 4.0.

Upgrading Groovy is non-trivial tasks and it's not possible for many frameworks to upgrade to the latest Groovy.

Solution

Revert to not exporting the Spock dependency into the POM as it was before 1.18.0

Benefit

Testcontainers Spock can be upgraded beyond 1.17.6 for developers not using yet Groovy 4

Alternatives

Publish the Spock artifacts fore ach Groovy version the same way how Spock is doing

Hi @musketyr, great catch! This is similar to what happened with junit jupiter. So, this should apply to spock as well. However, I'm not sure about how to handle the different versions 🤔 My initial thought is using the minimum version in the module and create some examples for the other two versions and test compatibility. Unless, just testing with the minimum ensures it works with the major versions.

I don't think the API is different between these variants of versions. Only the pulled transient dependency is what matters. It should be safe to use the lowest Groovy version possible (2.3-groovy-2.5) and if there is a higher one in the resolution graph then it will win.

@melix haven't you have to problem with https://github.com/micronaut-projects/micronaut-test-resources? or do you always have a good match of Spock and Groovy? I would like to hear your expert voice here.
