What does maven do?

Maven is a tool for building and managing Java projects. The main purposes are: 1. Dependency management, to help developers manage the external dependency libraries required for the project; 2. Build management, to execute the project's construction process, including compilation, testing, packaging and deployment, etc.; 3. Standardized project structure, providing a Standard project structure makes it easier for different developers to understand and collaborate; 4. Project document generation, automatically generate documents based on the project's configuration file and annotation information; 5. Support multi-module project management; 6. Unification of build configurations Management and so on.

Maven is a tool for building and managing Java projects. It provides a consistent project structure that helps developers manage tasks such as project dependencies, build processes, and documentation generation. The following are some of the main functions and uses of Maven:

Dependency Management: Maven can help developers manage the external dependency libraries required by the project. Developers only need to declare the required dependencies in the project's configuration file, and Maven will automatically download and manage these dependencies. This greatly simplifies the process of project configuration and management.

Build management: Maven can execute the project's build process, including compilation, testing, packaging and deployment, etc. Developers can use the commands provided by Maven to perform these tasks without having to manually write complex build scripts.

Standardized project structure: Maven provides a standard project structure, making it easier for different developers to understand and collaborate. This project structure defines the location and naming convention for source code, resource files, test code, configuration files, etc.

Project document generation: Maven can automatically generate documents based on the project's configuration file and annotation information. Developers can use Maven plug-ins to generate various types of documentation, such as API documentation, user manuals, etc.

Project report generation: Maven can generate various project reports, such as test coverage reports, code quality reports, etc. These reports help developers understand the health of their projects and guide them toward optimization and improvement.

Multi-module project management: Maven supports the management and construction of multi-module projects. Developers can divide a large project into multiple modules, each of which can be built and tested independently. This can improve development efficiency and make the dependencies between modules clearer and more controllable.

Unified management of build configuration: Maven uses an XML format configuration file to manage the project's build configuration. This configuration file can be managed by a version control system for sharing and collaboration among team members. Developers can customize the project's build process by modifying the configuration file without modifying the build script.

Maven is a powerful build tool that can help developers manage project dependencies, build processes, document generation and other tasks. It provides a standardized project structure and configuration method, making project management simpler and more reliable. Using Maven can improve development efficiency, reduce configuration errors, and make projects easier to maintain and collaborate on.
