Managing Java dependencies effectively is crucial for maintaining a secure and efficient application. By following best practices, developers can avoid common pitfalls such as outdated libraries, compatibility issues, and security vulnerabilities. A well-planned strategy for selecting, updating, and removing dependencies can help prevent these problems and ensure the overall quality of the application. The use of repository managers, dependency scanning tools like Snyk, and plugins in package managers can greatly aid in managing Java dependencies. By adopting a proactive approach to dependency management, developers can create a solid foundation for their Java applications and maintain them securely over time.
