5. Dependencies
6. Library • A collection of resources (cl a sses) • A J a v a Archive, or JAR f ile, cont a ins a ll of the v a rious components th a t m a ke up a self- cont a ined, execut a ble J a v a a pplic a tion or, most commonly, a J a v a libr a ry to which a J a v a Runtime Environment c a n link. 6
7. jar-download.com 7
8. • Build m a n a gement tool • M a ven a utom a tes dependency m a n a gement by a utom a tic a lly downlo a ding required libr a ries a nd their dependencies, ensuring consistent builds with speci f ied versions. • In contr a st, m a nu a lly downlo a ding JARs is l a bor-intensive a nd error-prone. 8
9. • The project object model (POM) f ile describes a project a nd its dependencies. • A st a nd a rdized directory form a t. • Repositories where third-p a rty softw a re is stored a nd discovered. 9
