This means that all constraints listed in a platform would not add a dependency unless another component brings it in: they can be seen as _recommendations_.

[NOTE]
====
For example, if a platform declares a constraint on `org:foo:1.1`, and that nothing else brings in a dependency on `foo`, `foo` will _not_ appear in the graph.

                warnings.addUnsupported(String.format("%s:%s:%s declared with Gradle attributes", dependency.getGroup(), dependency.getName(), dependency.getVersion()));
            }
