What core functionality does the Maven tool provide for managing Java projects?

Maven is a tool for managing Java projects that provides:

• Dependency management: automatically downloads and updates libraries needed by the project.
• Standardized project structure: simplifies organization of code and resources.
• Build automation: compilation, testing, packaging into jar/war, and other tasks.
• Project lifecycle management: build, test, deploy phases.

Example command for building a project:

mvn clean install

This command cleans previous builds and rebuilds the project, including running tests.
