If your Artifactory installation grows of many Gb each day - althought you do not deploy so many new artifacts. I suggest you to look under the repositories settings.

All your local repositories are configured as default with Snapshot Version Behavior = Non-Unique. As stated in the manual, all deployed SNAPSHOTS with be keep with unique time-stamp and build number suffix in the background (and you’ll only see one version in the tree).

I recommend you to switch to Non-Unique. In that mode Artifactory should only keep the N latest Snapshot of an groupid/artifact/name file.  So you’ll be able to keep the repository size under control.

Maven Tips and Tricks: Optimizing with the Maven Dependency Plugin

On larger projects, additional dependencies often tend to creep into a POM as the number of dependencies grow. As dependencies change, you are often left with dependencies that are not being used, and just as often, you may forget to declare explicit dependencies for libraries you require. Because Maven 2.x includes transitive dependencies in the compile scope, your project may compile properly but fail to run in production. Consider a case where a project uses classes from a widely used project such as Jakarta Commons BeanUtils. Instead of declaring an explicit dependency on BeanUtils, your project simply relies on a project like Hibernate that references BeanUtils as a transitive dependency. Your project may compile successfully and run just fine, but if you upgrade to a new version of Hibernate that doesn’t depend on BeanUtils, you’ll start to get compile and runtime errors, and it won’t be immediately obvious why your project stopped compiling.
