Maven Scope Explained

The scope attribute of Maven is used to specify the scope of dependencies, that is, at which stages the dependency can be used. The scope attribute has the following possible values:

1. Default value: indicates that the dependency is available during the compile, test, and run phases.
2. Indicate that this dependency is available during the compilation and testing phases, but will be provided by the container during the runtime phase, such as servlet-api.
3. The dependency is only available during runtime and testing, and will not be compiled.
4. test: This dependency is only available during the testing phase and will not be involved in compilation or execution.
5. The system indicates that the dependency is present in the local system and is imported using the specified systemPath.

By using the scope attribute, you can effectively control the availability of dependencies in different stages to avoid unnecessary dependencies affecting the project’s build and deployment.
