== Registering a build service and connecting it to a task

To create a build service, you register the service instance using the link:{javadocPath}/org/gradle/api/services/BuildServiceRegistry.html#registerIfAbsent-java.lang.String-java.lang.Class-org.gradle.api.Action-[BuildServiceRegistry.registerIfAbsent()] method.
Registering the service does not create the service instance.

Other tasks should be modified in their own configuration action:

val verificationTask by tasks.registering {
    // Configure verificationTask

    val compileClasspath: FileCollection = sourceSets["main"].compileClasspath

    tasks {

        val extractPrecompiledScriptPluginPlugins by registering(ExtractPrecompiledScriptPluginPlugins::class) {
            plugins = scriptPlugins
            outputDir.set(extractedPluginsBlocks)
        }

// are the configuration of the bootstrap token and all the setting which are specific to the node where kubeadm
// is executed, including:
//
// - NodeRegistration, that holds fields that relate to registering the new node to the cluster;
// use it to customize the node name, the CRI socket to use or any other settings that should apply to this
// node only (e.g. the node ip).
//

<3> Implement a custom task type called `MyCopyTask` which extends `DefaultTask` and defines the `copyFiles` task action.

=== 1. Registering tasks

You define actions for Gradle to take by registering tasks in build scripts or plugins.

Tasks are defined using strings for task names:

====

        '''

        then:
        succeeds "fromAfterEvaluate"

        and:
        output.contains "value: from after evaluate and from container rule and from rule"
    }

    def "registering a creation rule for a task that is already defined using legacy DSL"() {
        when:
        buildFile << """
            class MyPlugin extends RuleSource {
                @Mutate

	// +optional
	BootstrapTokens []bootstraptokenv1.BootstrapToken `json:"bootstrapTokens,omitempty"`

	// NodeRegistration holds fields that relate to registering the new control-plane node to the cluster
	// +optional
	NodeRegistration NodeRegistrationOptions `json:"nodeRegistration,omitempty"`
