Build Phases

Phase 1. Initialization

• Detects the settings.gradle(.kts) file.
• Creates a Settings instance.
• Evaluates the settings file to determine which projects (and included builds) make up the build.
• Creates a Project instance for every project.

Phase 2. Configuration

• Evaluates the build scripts, build.gradle(.kts), of every project participating in the build.
• Creates a task graph for requested tasks.

Phase 3. Execution

• Schedules and executes the selected tasks.
• Dependencies between tasks determine execution order.
• Execution of tasks can occur in parallel.

[settings.gradle]
rootProject.name = 'basic'
println 'This is executed during the initialization phase.'

[build.gradle]
println 'This is executed during the configuration phase.'

tasks.register('configured') {
    println 'This is also executed during the configuration phase, because :configured is used in the build.'
}

tasks.register('test') {
    doLast {
        println 'This is executed during the execution phase.'
    }
}

tasks.register('testBoth') {
	doFirst {
	  println 'This is executed first during the execution phase.'
	}
	doLast {
	  println 'This is executed last during the execution phase.'
	}
	println 'This is executed during the configuration phase as well, because :testBoth is used in the build.'
}

• The following command executes the test and testBoth tasks specified above. Because Gradle only configures requested tasks and their dependencies, the configured task never configures: ```

  gradle test testBoth This is executed during the initialization phase.

Configure project : This is executed during the configuration phase. This is executed during the configuration phase as well, because :testBoth is used in the build.

Task :test This is executed during the execution phase.

Task :testBoth This is executed first during the execution phase. This is executed last during the execution phase.

BUILD SUCCESSFUL in 0s 2 actionable tasks: 2 executed ```
