This allows a multi-variant plugin that depends on other plugins to access their APIs, which are exclusively provided in their version-specific variants.

This snippet makes the <<#plugin-with-variants,plugin variant `gradle7` defined above>> consume the matching variants of its dependencies on other multi-variant plugins:

[[sec:verification_category]]

[WARNING]
====
When the `Category` attribute is present with the incubating value `org.gradle.category=verification` on a variant, that variant is considered to be a verification-time only variant.

These variants are meant to contain only the results of running verification tasks, such as test results or code coverage reports.
