Você pode definir dependências que por sua vez definem suas próprias dependências.

No fim, uma árvore hierárquica de dependências é criadas, e o sistema de **Injeção de Dependência** toma conta de resolver todas essas dependências (e as sub-dependências delas) para você, e provê (injeta) os resultados em cada passo.

            throws ArtifactMetadataRetrievalException {
        Set<Artifact> dependencies = new HashSet<>();

        if ("g".equals(artifact.getArtifactId())) {
            Artifact a = null;
            try {
                a = factory.createBuildArtifact("org.apache.maven", "h", "1.0", "jar");
                dependencies.add(a);
            } catch (Exception e) {

## Create a `get_current_user` dependency { #create-a-get-current-user-dependency }

Let's create a dependency `get_current_user`.

Remember that dependencies can have sub-dependencies?

`get_current_user` will have a dependency with the same `oauth2_scheme` we created before.

 * 1. dependencyManagement should override the scope of transitive dependencies.
 * 2. Direct dependencies should override the scope of dependencyManagement.
 * 3. Direct dependencies should inherit scope from dependencyManagement when

## Dependencies { #dependencies }

FastAPI depends on Pydantic and Starlette.

### `standard` Dependencies { #standard-dependencies }

When you install FastAPI with `pip install "fastapi[standard]"` it comes with the `standard` group of optional dependencies:
