=== 3. API Reference

Gradle's API references can be found in the links below:

- link:{javadocPath}/index.html[Javadocs^]
- link:{groovyDslPath}/index.html[Groovy DSL Reference^]

[[sec:settings_file_script]]
== Settings script

The settings file is a script.
It is either a `settings.gradle` file written in Groovy or a `settings.gradle.kts` file in Kotlin.

The link:{groovyDslPath}/index.html[Groovy DSL^] and the link:{kotlinDslPath}/index.html[Kotlin DSL^] are the only accepted languages for Gradle scripts.

The settings file is typically found in the root directory of the project.

Let's take a look at an example and break it down:

{{- end}}
{{- if ne $.ImagePullSecretName "" }}
      imagePullSecrets:
      - name: {{ $.ImagePullSecretName }}
{{- end }}
      containers:
{{- if and
  (ne (index $subset.Annotations "sidecar.istio.io/inject") "false")
  (ne (index $subset.Annotations "inject.istio.io/templates") "grpc")
  ($.OverlayIstioProxy)
}}
      - name: istio-proxy
        image: auto
        imagePullPolicy: {{ $.ImagePullPolicy }}

	CALL	AX
	MOVQ	32(SP), SP

	MOVQ	AX, CX	// TLS index

	// Assert that slot is less than 64 so we can use _TEB->TlsSlots
	CMPQ	CX, $64
	JB	ok

	// Fallback to the TEB arbitrary pointer.
	// TODO: don't use the arbitrary pointer (see go.dev/issue/59824)
	MOVQ	$TEB_ArbitraryPtr, CX
	JMP	settls
ok:
	// Convert the TLS index at CX into
	// an offset from TEB_TlsSlots.
	SHLQ	$3, CX

[[sec:build_script]]
== Build scripts

The build script is either a `build.gradle` file written in Groovy or a `build.gradle.kts` file in Kotlin.

The link:{groovyDslPath}/index.html[Groovy DSL^] and the link:{kotlinDslPath}/index.html[Kotlin DSL^] are the only accepted languages for Gradle scripts.

Let's take a look at an example and break it down:
