Spotless is leaking Java 11 dependency.

[JavierSegoviaCordoba]

Summary

I have a published plugin that is configuring Spotless and I apply it in all my projects, after upgrading Spotless to 6.0.3, My project, which is Java 8, which is applying my published plugin can't be compiled because of a dependency is Java 11.

The consumer was configured to find a runtime of a library compatible with Java 11, 
packaged as a jar, preferably optimized for standard JVMs, and its dependencies 
declared externally, as well as attribute 'org.jetbrains.kotlin.platform.type' with 
value 'jvm'. However we cannot choose between the following variants of project :mokoki-core:
    - jvmRuntimeElements
    - spotless1316845943

spotless1316845943 this should not be appearing there I think, but it is being leaked into the project.

I am not having this issue with 6.0.2, but 6.0.4 has this issue too, not only 6.0.3.

• Gradle 7.3.1
• Windows 10

My published plugin is adding Spotless as a dependency (implementation(...)). So the consumer hasn't to add Spotless to the classpath itself, because the plugin has the dependency directly.
