== Step 1. Viewing available Tasks
A _task_ is a basic unit of work that can be done by Gradle as part of the build.

In the `tutorial` directory, enter the command below to list all the available tasks in the project:
[source,text]
----
$ ./gradlew tasks
----

The list includes tasks contributed by the `application` plugin and the plugin it applies:

[source,text]

    absl::flat_hash_set<Operation*> last_writes = GetLastWrites(resource);
    stack_down_.back()[resource] = last_writes;
  }
  Enter();
}

void SideEffectAnalysisInfo::Lateral() {
  Exit();
  Enter();
}

void SideEffectAnalysisInfo::Up() {
  Exit();
  for (const auto& [resource, last_writes] : stack_up_.back()) {
    SetLastWrites(resource, last_writes);
  }

Но в нашем случае одно и то же приложение **FastAPI** будет работать с API и аутентификацией.

Итак, рассмотрим его с этой упрощенной точки зрения:

* Пользователь вводит на фронтенде `имя пользователя` и `пароль` и нажимает `Enter`.
* Фронтенд (работающий в браузере пользователя) отправляет эти `имя пользователя` и `пароль` на определенный URL в нашем API (объявленный с помощью параметра `tokenUrl="token"`).

	traceEvGoBlock             // goroutine blocks [timestamp, reason, stack ID]
	traceEvGoUnblock           // goroutine is unblocked [timestamp, goroutine ID, goroutine seq, stack ID]
	traceEvGoSyscallBegin      // syscall enter [timestamp, P seq, stack ID]
	traceEvGoSyscallEnd        // syscall exit [timestamp]
	traceEvGoSyscallEndBlocked // syscall exit and it blocked at some point [timestamp]

Betrachten wir es also aus dieser vereinfachten Sicht:

* Der Benutzer gibt den `username` und das `password` im Frontend ein und drückt `Enter`.
* Das Frontend (das im Browser des Benutzers läuft) sendet diesen `username` und das `password` an eine bestimmte URL in unserer API (deklariert mit `tokenUrl="token"`).

== Step 5. Viewing Dependencies in a Build Scan®
To view dependencies using a https://scans.gradle.com/[Build Scan], run the build task with an optional `--scan` flag.

In the `tutorial` directory, enter the command below and follow the prompt to accept the terms:
[source,text]
----
$ ./gradlew build --scan

BUILD SUCCESSFUL in 423ms
7 actionable tasks: 7 up-to-date

	// If the webhook is later added a new reconciliation request will trigger it to update
	if whc == nil {
		scope.Infof("Skip patching webhook, not found")
		return nil
	}

	scope.Debugf("Reconcile(enter)")
	defer func() { scope.Debugf("Reconcile(exit)") }()

	caBundle, err := util.LoadCABundle(c.o.CABundleWatcher)
	if err != nil {
		scope.Errorf("Failed to load CA bundle: %v", err)

Mas nesse caso, a mesma aplicação **FastAPI** irá lidar com a API e a autenticação.

Então, vamos rever de um ponto de vista simplificado:

* O usuário digita o `username` e a `senha` no frontend e aperta `Enter`.
* O frontend (rodando no browser do usuário) manda o `username` e a `senha` para uma URL específica na sua API (declarada com `tokenUrl="token"`).

	// termination complete.
	n := work.cycles.Load()
	gcWaitOnMark(n)

	// We're now in sweep N or later. Trigger GC cycle N+1, which
	// will first finish sweep N if necessary and then enter sweep
	// termination N+1.
	gcStart(gcTrigger{kind: gcTriggerCycle, n: n + 1})

	// Wait for mark termination N+1 to complete.
	gcWaitOnMark(n + 1)

	// Finish sweep N+1 before returning. We do this both to
