Managing Java dependencies efficiently can be streamlined using a Maven or Gradle repository, which provides secure and consistent access to shared dependencies in a centralized location. The JFrog cloud subscription, including tools like JFrog Artifactory, Xray, and Pipelines, facilitates the quick setup of local, remote, and virtual Maven/Gradle registries. The process involves logging into the environment, creating local and remote repositories to store custom and third-party dependencies, and establishing a virtual repository to manage these resources. Users need Maven or Gradle installed, along with the JFrog CLI, to configure and automate access to JFrog products. By following these steps, users can build projects by resolving dependencies from Artifactory and ultimately publish build information back to the repository for easy access and management within the JFrog platform.
