What are the different scopes available in Maven?

Maven provides several different scopes that can be used to define the visibility of a dependency.

• Compile: This is the default scope. Dependencies with this scope are available in all phases of the project, including compilation, testing, and runtime.
• Provided: Dependencies with this scope are required for compilation and testing, but are expected to be provided by the runtime deployment environment. These dependencies are not included in the final package.
• Runtime: Dependencies with this scope are not required for compilation but are required for execution. They are not included in the compilation classpath, but are available at runtime.
• Test: Dependencies with this scope are only available for the test compilation and execution phases, and are not included in the final package.
• System: This scope is similar to Provided, but allows you to specify the path to the dependency on the local system. It is not recommended, as it can cause portability issues.
• Import: This scope is used only on a dependency of type pom. It indicates that the specified POM should be replaced by the dependencies in that POM.

Understanding and correctly specifying the appropriate scope for each dependency in a Maven project is crucial for efficient project management and build performance.
