Standard Maven Project Structure
When you create a new Maven project, you will notice that it follows a strict directory layout. This standard structure is one of Maven's core strengths, as it ensures consistency across projects, simplifies build processes, and makes it easier for developers to understand any Maven-based codebase.
The default Maven directory structure looks like this:
README.md
1**Minimal Maven Project Structure with Comments**
com.example βββ my-maven-app/ βββ pom.xml # Project Object Model file: defines project configuration and dependencies βββ src/ βββ main/ β βββ java/ # Main application source code goes here β βββ resources/ # Application resources (e.g., config files) go here βββ test/ βββ java/ # Test source code (e.g., unit tests) goes here βββ resources/ # Test resources (e.g., test data) go here

src/main/java: contains the application's main source code;src/main/resources: contains non-code resources needed by the application, such as configuration files;src/test/java: contains unit test source code;src/test/resources: contains resources needed for testing, such as test data files;target: the output directory where Maven places compiled classes, packaged JARs, and other build artifacts.
Following this convention allows you to take advantage of Maven's automated build and testing features without extra configuration. Tools and plugins expect this layout, so adhering to it reduces errors and makes collaboration smoother when working with other developers.
