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
