How to list all gradle tasks?

You can use gradle tasks to list the tasks of a project. This will let you see the tasks that the Java plugin has added to your project. Here is a simple build.gradle file for an example:

defaultTasks 'clean', 'run'
						
task clean << {
        println 'Default Task - Cleaning!'
}
task run << {
        println 'Default Task - Running!'
}
task mySpecTask << {
        println "I'm not a default task!"
}

Run "gradle tasks"

Preemptive scheduling Vs Time slicing?

Preemptive scheduling: The highest priority task executes until it enters the waiting or dead states or a higher priority task comes into existence.

Time slicing: A task executes for a predefined slice of time and then reenters the pool of ready tasks. The scheduler then determines which task should execute next, based on priority and other factors.

Famous Quotations

Good judgment comes from experience, and experience comes from bad judgment.
