[JAVA] Making a Java Multi-Module

Last year, I joined the Scheduler service refactoring project at my company.

It was an opportunity to study Java Multi-Module, so I decided to publish about it.

 

1. Module

In the Oracle Java official documentation, a module is a union of packages.

It is also a reusable group that associates packages and resources.

At that time, each module could be developed, built, tested, and deployed independently.

 

 

2. Multi-Module

- A project with multiple modules is called a multi-module project

- It's common practice to split a project into smaller, interdependent modules

- In Gradle, a multi-project build is similar to a multi-module project

3. Why the "Multi-Module"

- Reduce human error when copying and pasting domains to different projects that work the same way.
  So, we can ensure the same domain(or code) in used across different projects.

 

- It makes building project easier.

- We can easily understand the features about modules.

4. Caution

But if you overuse it, it causes highly dependent code.
So, we should be mindful when using this architectural approach.
