| + | ====== scope ====== | ||
| + | ===== compile ===== | ||
| + | If none is specified, this one is ussed. The dependency is available in all classpath of the proyect and the dependencies are propagated among dependent projects | ||
| + | ===== provided ===== | ||
| + | The difference with compile is that it is supposed to be provided at runtime by the system, not by your application, so it has not to be packaged in your deployment. | ||
| + | It is not transitive and only available in compilation and test classpath | ||
| + | |||
| + | ===== runtime ===== | ||
| + | It means that the dependency is not required for compilation but for execution. It works in the runtime and test classpaths but not in the compile classpath. | ||
| + | |||
| + | ===== test ===== | ||
| + | The dependency with this scope is not required for normal use of the application, and it is only available for the test classpath. It is not transitive | ||
| + | ===== system ===== | ||
| + | Instead of provide the dependency by the system, you in the body of the dependency specify the path to it. It is attached to the deployment | ||
| + | |||
| + | ===== import ===== | ||
| + | Under this scope, the dependencies inside the tag <dependencyManagement> section are copied to where this dependency is (based on the groupId and the artifactId). | ||
| + | |||
| + | ====== Dependencies ====== | ||
| + | H2 database and jpa | ||
| + | |||
| + | <dependency> | ||
| + | <groupId>org.springframework.boot</groupId> | ||
| + | <artifactId>spring-boot-starter-data-jpa</artifactId> | ||
| + | </dependency> | ||
| + | <dependency> | ||
| + | <groupId>com.h2database</groupId> | ||
| + | <artifactId>h2</artifactId> | ||
| + | <scope>runtime</scope> | ||
| + | </dependency> | ||
| + | |||
| + | If instead of H2 database it is needed mysql: | ||
| + | |||
| + | <dependency> | ||
| + | <groupId>mysql</groupId> | ||
| + | <artifactId>mysql-connector-java</artifactId> | ||
| + | <scope>runtime</scope> | ||
| + | </dependency> | ||
