To see which tasks are available for a Gradle project we can invoke the tasks task. With this task all tasks are printed to the console with their description. To get more information about a specific task we can use the Gradle help task with the command-line option --task followed by the task name. Gradle prints out the path, type, description, group and optional options for the task.
