## Criar uma dependência `get_current_user` { #create-a-get-current-user-dependency }

Vamos criar uma dependência chamada `get_current_user`.

Lembra que as dependências podem ter subdependências?

`get_current_user` terá uma dependência com o mesmo `oauth2_scheme` que criamos antes.

                // The system scoped dependencies will be present in the classloader for the plugin
                return;
            }
        }

        fail("Can't find the system scoped dependency in the plugin artifacts.");
    }

    // -----------------------------------------------------------------------------------------------
    // Testing help

        assertNotNull(dep, "No dependencyManagement");
        List<?> list = dep.getDependencies();
        assertNotNull(list, "No dependencies");
        assertTrue(!list.isEmpty(), "Empty dependency list");

        Map<?, ?> map = projectToClone.getManagedVersionMap();
        assertNotNull(map, "No ManagedVersionMap");
        assertTrue(!map.isEmpty(), "ManagedVersionMap is empty");

kann auch als gültige **FastAPI**-Abhängigkeit verwendet werden.

Tatsächlich verwendet FastAPI diese beiden Dekoratoren intern.

Sie könnten damit beispielsweise eine Datenbanksession erstellen und diese nach Abschluss schließen.

This includes work such as compiling, testing and documenting software, plus sharing that software via publishing and dependency management.
This platform is agnostic to what kind of software is being developed.
It might be Java or Kotlin libraries running on the JVM, Gradle plugins, Android or iOS applications, C++ libraries, and so on.
