What is the role and purpose of a profile in Maven when managing project builds?

A profile in Maven is used to manage build configurations that can vary depending on the environment or goals. Profiles allow you to define different dependencies, plugins, compilation parameters, and other settings that are activated during the build.

For example, you can create a development profile with debugging parameters and another profile for production with optimizations and no tests.

Profiles enable:

• Changing build behavior without modifying the main POM.
• Managing dependencies and plugins for different environments.
• Activating settings via command line or automatically based on conditions (e.g., OS).

Example of profile activation:

mvn clean install -Pproduction
