=== Variant-dependent Tasks

The {cpp} Unit Test Plugin creates tasks based on the variants of the unit test component.
Read the <<building_cpp_projects.adoc#sec:introducing_build_variants-cpp,introduction to build variants>> for more information.
The following diagrams show the relationship between variant-dependent tasks.

 * the same set of capabilities as the feature itself. Since all variants of a feature are derived
 * from the same sources, they all expose the same API or "content" and thus provide the same
 * capabilities. Some variants may expose additional capabilities than those of its owning feature,
 * for example with fat jars.</p>
