In Maven, the difference between “mvn verify” and “mvn verify -U” commands lies in whether or not to force an update of the project’s dependencies.
The “mvn verify” command runs the project’s verification tests and uses locally cached dependencies.
The “mvn verify -U” command, on the other hand, forces an update of all dependencies before running the project’s verification tests. This means that Maven will check for the latest version of each dependency and download the latest version from the central repository (if available).
In summary, the “mvn verify -U” command is more time-consuming than the “mvn verify” command because it requires downloading all the latest versions of dependencies from the central repository. However, if your project depends on libraries that have been updated and you want to always use the latest version, then the “mvn verify -U” command may be more suitable for your needs.
