@vlsi, would this break anything in the way the build is configured?

[vlsi]

I wanted gradle plugin to support Gradle 6.x (so the ones who use Gradle 6 could use the plugin without migrating the build first), and it would require building with 6.8 to make it possible.

[loosebazooka]

Should we add a matrix to the gradle tests to see that the gradle plugin tests still work with 6.x?

[vlsi]

AFAIK it will fail.
The current minimal supported version is 7.2, however, I did not invest time in expanding the set of supported versions.

	// Make the test faster, and skip extra tests with the configuration cache to reduce OIDC flows
	// Gradle 7.2 fails with "No service of type ObjectFactory available in default services"
	return listOf(arguments("7.3", ConfigurationCache.OFF))
