Add Cobertura report

[cromefire]

I haven't drilled down on the XML format specifically and there doesn't seem to be any indication of it's format (from the code it seems to be agent specific?).

GitLab only supports the cobertura format natively (conversion from JaCoCo is available, but needs some python script), so it would be really cool if a native cobertura report would be available for fast and easy integration into GitLab.

By the way, the IntelliJ agent generates XML with the same format as JaCoCo (with some differences that will be removed in future releases).
You can try to use a JaCoCo converter for IntelliJ's XML file and if there are any issues with it, we will fix format.

This is not an ideal solution, since it's involves 3rd party converters like registry.gitlab.com/haynes/jacoco2cobertura:1.0.7 and additional setup (extra step in pipeline, extra image)

jacoco2cobertura fails to convert IntelliJ's XML file, because it doesn't contain sessioninfo element with start attribute.
Also it fails on branch-rate and complexity counters because kover supports only line counters for now.

This plugin supports sessioninfo:

But doesn't support other sourcesets than main yet

Any update/plans with this feature in 2024?

GitLab now supports JaCoCo coverage reports, but it doesn't appear to populate in the merge request. Has anyone else had this experience?

Link?

@IRus Here’s the link to GitLab’s docs: https://docs.gitlab.com/ee/ci/testing/test_coverage_visualization/jacoco.html

Just pay attention to this:

Introduced in GitLab 17.3 with a flag named jacoco_coverage_reports. Disabled by default.

This task will be taken into account when migrating to Kotlin Gradle Plugin.

In the future, it will be moved to the Kotlin task tracker, or closed if it loses relevance.
