How do transitive dependencies arise and what challenges are associated with them in projects?

Transitive dependencies occur when your project directly depends on library A, and library A in turn depends on library B. Thus, library B becomes a transitive dependency of your project.

Challenges associated with transitive dependencies:

• Version conflicts: different libraries may require different versions of the same dependency, leading to conflicts and errors during build or runtime.
• Increased project size: a large number of transitive dependencies can significantly increase the size of the final application.
• Management complexity: it is difficult to track which libraries and versions are used, especially if transitive dependencies are deeply nested.
• Security: transitive dependencies may contain vulnerabilities that you are not directly aware of.

Build tools (Maven, Gradle) are used to manage transitive dependencies, allowing you to view the dependency tree, exclude unnecessary or conflicting versions, and lock dependency versions.
