Issues while running multiple CucumberWithSerenity runners in parallel

[pogodins]

Since Cucumber with Junit can run only feature files in parallel I was looking for a solution to generate test runners for every scenario.
Test runners generation intself works fine with https://github.com/temyers/cucumber-jvm-parallel-plugin.

However, in case of multiple runners being executed in parallel, I'm getting issues with Serenity, namely:

• "No BaseStepListener has been registered" error when executing runners in parallel which are pointing to different feature files.
  
  Code can be found here: https://github.com/pogodins/serenity-cucumber-starter/tree/ParallelRunnersDifferentFeatures
• Broken Serenity report when executing runners in parallel from the same feature file
  
  Code example: https://github.com/pogodins/serenity-cucumber-starter/tree/ParallelRunnersSameFeature

@wakaleo could you please check if I configured properly test execution?
If I did it right, it would be really helpful to fix these issues as a lot of people would benefit from running scenarios in parallel.

When I'm able to execute multiple runners in parallel, I could write an insrtuction on how to generate runners and configure Serenity.

https://github.com/temyers/cucumber-jvm-parallel-plugin is no longer supported.

I've written up how to run Cucumber features in parallel in https://johnfergusonsmart.com/parallel-test-execution-with-cucumber-and-serenity-bdd/ - parallel scenario execution isn't supported.

Hi @wakaleo, thanks for your feedback!
My issue is not about cucumber plugin itself, and I know how to run feature files in parallel.

The problem for me is that Serenity doesn't work with parallel CucumberWithSerenity runners as I showed in my example project.
In example projects I created runners pointing to different scenarios manually (without any plugin).
What I expect is that manually created runners can be executed in parallel on the same machine.

Could you please suggest if I misconfigured my code or how we can fix Serenity to execute Cucumber runners in parallel?

Last time i tried it seemed to work fine with multiple runners globalworming/serenity-cucumber-starter@875c326#diff-7fa6615a67c71eb463e49be76cbe914bcc440e85b4eec68ef80e3ae9b16ad967

This seems to work fine in 3.2.0 - please reopen if the issue still occurs for you.

The behavior is still the same for multiple runners with Serenity 3.2.0. Repository with example code is updated by me now.
@wakaleo could you please share the configuration which worked for you?
