A separate main to launch JUnit Platform

[mpkorstanje]

🤔 What's the problem you're trying to solve?

When launched through io.cucumber.core.cli.Main Cucumber will use cucumber.properties. When launched through the JUnit Platform the junit-platform.properties file is used.

This difference can be confusing for novice and advanced users who use Intelij IDEA. And unfortunately JetBrains has made little progres improving on this (see IDEA-227508).

✨ What's your proposed solution?

Create a new main method that maps the CLI arguments to the JUnit Platform and runs Cucumber. This main can then be used in IDEAs run configuration.

⛏ Have you considered any alternatives or workarounds?

Reading cucumber.properties in the JUnit Platform is an option. Though because Cucumber and JUnit have different semantics around merging properties this doesn't seem feasible.

Alternatively Cucumber could change it's property reading mechanism to be more sane. But that would be something for the next major release.

Or I could implement a better Cucumber plugin. Though I should probably do it in VS Code. Maybe that will get JetBrains attention. My subscription certainly doesn't.

Additional idea. Consider adding a --junit-platform flag or subcommand to the regular CLI that will delegate to the JUnit Platform for reduced friction.
