Maven tutorial
Maven is a build tool and project management tool that can be used for the OHIM project. It provides features like project portability, simple dependency management, and extensibility through plugins. Maven uses a project object model (POM) to manage a project's build configuration and dependencies. It defines a standard directory structure for projects and supports features like profiles, dependencies, plugins and a build lifecycle.

- 30. 30 DEPENDENCIES • compile :- the project needs this dependency at compile time - compile is the default scope; • provided : - provided dependencies are used when you expect the JDK or a container to provide them. -They are not transitive. - Ex: servlet API • runtime : - runtime dependencies are required to execute and test the system, but they are not required for compilation. - Ex: JDBC driver • test : - test-scoped dependencies are not required during the normal operation of an application - they are available only during test compilation and execution phases. • system: -The system scope is similar to provided except that you have to provide an explicit path to the JAR on the local file system. ( NOT RECOMMENDED)
