Any example of running a gradle task with the Launcher API?

[wazzeps]

I would like to understand how I can run a Gradle task that will only run tests using the Launcher API.

Should this be a simple main method call? Or is there Gradle integration with the JUnit Platform?

Gradle actually uses the Launcher API itself to run tests on the JUnit Platform.

Yes, Gradle has built-in support for the JUnit Platform in the test task.

If you need something different than what Gradle's test task offers, yes, you could create your own main() method or custom Gradle task to interact with the Launcher API as you wish.
