=== JVM ecosystem specific attributes

In addition to the ecosystem independent attributes defined above, the JVM ecosystem adds the following attribute:

Gradle provides an improved model for this, which doesn't have the weakness of classifiers: attributes.

In particular, in the Java ecosystem, Gradle provides a built-in attribute that library authors can use to express compatibility with the Java ecosystem: `org.gradle.jvm.version`.
This attribute expresses the _minimal version that a consumer must have in order to work properly_.

The values `java-api-*` and `java-runtime-*` are now deprecated and replaced by a new combination.

The values for the Java ecosystem are now limited to `java-api` / `java-runtime` combined with the relevant value for `org.gradle.libraryelements`.

Values for the native ecosystem remain unaffected.
