If you have a few years of experience in the Java ecosystem, and you're interested in sharing that experience with the community (and getting paid for your work of course), have a look at the "Write for Us" page. When you run a build or execute a maven goal, these dependencies are resolved, and are then loaded from the local repository. We can make the use of the dependency scopes in our dependency tags inside the pom.xml file that will help to manage the transitive dependencies and also help in being available for the classpaths where that dependency is required by choosing the appropriate dependency scope for our dependency. The Maven dependency:analyze goal helps to find those dependencies. Import indicates that this dependency should be replaced with all effective dependencies declared in it's POM: Each dependency scope affects transitive dependencies in its own way.
