Sole ./gradlew check does not work.

[snazy]

After the bump of the com.diffplug.gradle.spotless plugin from 6.6.0 to 6.6.1 (#178), just running ./gradlew check starts to fail w/ the below error. Interestingly CI is not affected, it seems that a ./gradlew assemble check works around the issue.

From a very brief look it seems that spottless 6.6.1 creates a spotless123 variant that "conflicts" with the runtimeElements variant.

$ ./gradlew check -x jmh 
Configuration on demand is an incubating feature.
