• Build management tool • Maven automates dependency management by automatically downloading required libraries and their dependencies, ensuring consistent builds with specified versions. • In contrast, manually downloading JARs is labor-intensive and error-prone. 25 

• The project object model (POM) file describes a project and its dependencies. • A standardized directory format. • Repositories where third-party software is stored and discovered. 26
