Filtering methods from code coverage

[Сергей Капралов]

Good day.

I have a tool, which besides other things generates equals and hashCode methods for classes (it's my own tool, which is not somehow related or dependent on lombok or similar stuff). And my intention is to make somehow these methods excluded from JaCoCo coverage reports. What options do I have in JaCoCo latest version?

Investigating opportunities on subj, described in https://github.com/jacoco/jacoco/wiki/FilteringOptions, I found out these potential ways of solving the problem:
1. Acceptable way for me would be to annotate equals and hashCode with some @ExcludeFromCodeCoverage and call it a day, but as I got it from https://github.com/jacoco/jacoco/issues/14, feature perspectives looks quite shady for me (or maybe I got it wrong?).
2. There is a dirty hacky way which works for me in 0.8.0 - to create a fake annotation lombok.Generated in the project and annotate equals/hashCode with it. But it is... well... dirty.
...
Any other options?

Hi,

actually option 2 is the only one that works with the current release: Annotate with one of the existing annotations @lombok.Generated or @groovy.transform.Generated. If you define the annotations yourself make sure the retention is CLASS.

If future versions of JaCoCo may come with their own annotation (like @ExcludeFromCodeCoverage) would a dependency on this JaCoCo annotations work better for you?

Cheers,

A bit better, yes.

Honestly, the best option for me would be to have some "excludes" patterns in build plugins. I saw this https://github.com/jacoco/jacoco/wiki/FilteringOptions#filters-based-on-excludes-configuration explaination but still haven't got it how annotations way makes it different.
