Pre-requisite:

You can read & understand this series without type any code.
However, if you want to try the process out, you need to have a ZooKeeper up and running somewhere.
So you may find one or set up one.

Step 1 Create a new project in IDEA

File -> New -> Project

Select to build with Maven

Specify the information

Click 'Finish' to create the project

Open in a new window

Step 2 Create an service interface that exposes some thing

add a package

enter name of the package

Create a class inside the package

Name it and select the type to be interface

Expose an interface

Step 3 Add an implementation for the service

We need to add an implementation for the service to do the real work.

Create a new class

Name and select type

Check the initial status after creation

Make it to implement the service interface

Select to implement the method automatically

Confirm

Add some simple output code

Step 4 Build now to see that the code is good

'View' -> 'Tool Windows' -> 'Maven Projects' to show the Maven tool-view

Check the effect of the tool-view

Double-click on 'compile' and see that we build successfully
