* The [Gradle Tooling API client](https://docs.gradle.org/8.8/userguide/third_party_integration.html#embedding)
  * This requires a Java application, and thus runtime, to run the tooling API client

As indicated, each of those components require a Java runtime to run.

The recommended way of invoking Gradle is to use the Gradle Wrapper.

Wenn ein Client versucht, einige **zusätzliche** Daten in den **Query-Parametern** zu senden, erhält er eine **Error-<abbr title="Response – Antwort: Daten, die der Server zum anfragenden Client zurücksendet">Response</abbr>**.

Wenn der Client beispielsweise versucht, einen `tool` Query-Parameter mit dem Wert `plumbus` zu senden, wie:

```http

// Dsync represents dsync client object which is initialized with
// authenticated clients, used to initiate lock REST calls.
type Dsync struct {
	// List of rest client objects, one per lock server.
	GetLockers func() ([]NetLocker, string)

	// Timeouts to apply.
	Timeouts Timeouts
