Maven Scope Explained

The scope in Maven is used to specify the visibility and usage scope of dependencies in different build environments.

Common values for scope include:

1. compile: default value, indicating that dependencies are visible during compilation, testing, and execution, and will be included in the final build result.
2. Indicates that the dependencies are visible during compilation and testing, but provided by the container at runtime (such as a Servlet container), thus they are not included in the build result.
3. Runtime indicates that dependencies are visible during testing and execution, but do not need to be visible during compile time.
4. Dependency marked as test means it is only visible during testing and will not be included in the compilation or runtime results.
5. system: indicates that the dependency exists in the local system and requires the systemPath attribute to specify the path of the dependency. This scope is rarely used and is mainly used to address the absence of common libraries in a project.

By using different scopes, we can control the visibility and usage range of dependencies in different stages of the build process, thereby enhancing flexibility and efficiency.
